[Bug 1967636] [NEW] Ubuntu ubuntu-22.04: Yelp does not display the Ubuntu documentation

[Simos Xenitellis ]

Public bug reported:

Yelp does not show the Ubuntu documentation (Ubuntu User Guide) when you
launch it.

Tested both with the en_US and el_GR locales.

What happens: When you click on Help, the yelp application opens but the window 
is blank, empty.
What should happen: Yelp should display the Ubuntu documentation.

What is going on though: Yelp does open the Ubuntu documentation but
everything appears white. As if an overlay is covering the
documentation. See attached screenshots.

[Simos Xenitellis ]

Here I typed Cltr+A to  Select All in the Yelp window and blindly tried
to move the selected content with the mouse.

Indeed, the documentation is there but it appears all white in the Yelp
window.

[Bug 1914077] [NEW] Add Greek langpack to LibreOffice snap package

[Simos Xenitellis ]

Public bug reported:

Currently, the Libreoffice snap package supports the following UI
languages:

English (USA)
Catalan
Chinese (Traditional)
French (France)
German
Hungarian
Italian
Japanese
Polish
Portuguese (both Portugal and Brazil)
Russian
Spanish (Spain)
Turkish

Greek is spoken by 11.1m people, which is a similar number for Catalan and 
Hundarian.
In the Greek Public Service (for example, the judicial system), there are many 
Ubuntu laptops with no upgrade path for the latest version of LibreOffice.

Can you please add Greek to the list?

[Bug 1875062] Re: Incorrect keyboard layout for selecting username and password during install of 20.04

[Simos Xenitellis ]

I suggest to change the title of this report to something like
"[20.04] Keyboard layout not enabled immediately during installation when 
typing username/password".

It looks like an issue of not activating the selected keyboard layout
during the installation, in order to type your
username/password/computer name.

I have not tested for this and I do not recall an issue, probably
because I use the English US layout as the primary layout.

[Bug 1872123] Re: [20.04] X session fails to start on 440 and kernel 5.4.0-21 (but 5.4.0-18 works)

[Simos Xenitellis ]

I have installed from scratch Ubuntu Daily 20200412, which is still at
the Linux 5.4.0-21 kernel.

I was not able to replicate the issue that I was facing, therefore for
me I would mark this report as INVALID.

@magean: I have just reinstalled Ubuntu Daily and I got the proprietary
drivers instead of nouveau. During the installation, I ticked the option
to receive proprietary graphics drivers and WiFi firmware.

The little gear to switch between an X11 and Wayland session should
appear as soon as you start typing the password. It does not appear by
default.

In your case, I would try to install again the fresh Daily, and try to
figure out a reproducible list of steps.

Do you want to create a new report that specifically describes the issue that 
you are facing? 
As far as I understand, the issue you are getting is related to switching 
between nouveau and proprietary NVidia?

[Simos Xenitellis ]

Public bug reported:

I am testing Ubuntu 20.04. This system has an NVidia GPU, with nvidia-
driver 440.64.

With Linux kernel 5.4.0-18, I can login successfully to an X session (default 
GNOME).
With Linux kernel 5.4.0-21, I fail to login to an X session. When I put my 
password and press Enter to login, the screen blanks, and within a second 
returns back to the login screen.


With Linux kernel 5.4.0-21 and Wayland session, it works and I can login.

[Bug 1285444] Re: Login Successful, Desktop Never Loads

[Simos Xenitellis ]

This bug report is from 2014.

I get this issue (return almost immediately to the login screen) in Ubuntu 
20.04 Beta with the 5.4.0-21 kernel. 
But with the immediate previous kernel, 5.4.0-18 works and I get a desktop 
session.

Anyone who found an existing report on such an issue?

[Bug 1869372] [NEW] Popping/crackling noise when sound card wakes from powersaving

[Simos Xenitellis ]

Public bug reported:

I could not find an existing report on this.
When Ubuntu 20.04 does powersaving, the audio card powers down.
When the card powers up again, it emits a short annoying popping/crackling 
noise, then audio plays just fine.

The workaround is to disable power-saving for the audio card, by adding

options snd_hda_intel power_save=0 power_save_controller=N

to a file in /etc/modprobe.d/alsa-intel-no-powersave.conf

and then reboot.

The system is largely unresponsive. I got this though:

It appears that the memory has been exhausted.
Do kernel errors from resource exhaustion count as bugs?

[Bug 1686338] Re: cloud-init fails if no network config is set

[Simos Xenitellis ]

I made a change in the cloud-init configuration:

--- version1.profile2018-07-24 20:32:06.054307582 +0300
+++ version1.profile.after  2018-07-24 20:32:32.890558707 +0300
@@ -1,5 +1,5 @@
 config:
-  user.network-config: |
+  user.user-data: |
 network:
 version: 1
 config:

and now cloud-init works as expected on LXD.

I still get a non-fatal warning: 2018-07-24 17:29:04,515 -
__init__.py[WARNING]: Unhandled non-multipart (text/x-not-multipart)
userdata: 'b'network:'...'

Relevant discussion: https://github.com/lxc/lxd/issues/3347

Therefore, the workaround should be not to use `network-config` for
network configuration but use `user-data` instead?

[Bug 1686338] Re: cloud-init fails if no network config is set

[Simos Xenitellis ]

The following relate to LXD and the LXD container images for 16.04 and
18.04. Both container images have cloud-init 18.2 (18.2-4-g05926e48).

SUMMARY
cloud-init fails to set up networking if a container is launched with 
cloud-init networking instructions.

WHAT WAS TESTED 
16.04 container image with cloud-init v1 and v2 configurations.
18.04 container image with cloud-init v1 and v2 configurations.

HOW TO REPRODUCE

1. Set up LXD

2. Create a new LXD profile. Create first this file (mycloudinit.profile)
---
$ cat mycloudinit.profile 
config:
  user.network-config: |
network:
version: 1
config:
- type: physical
  name: eth0
  subnets:
- type: dhcp
description: LXD profile with some cloud-init network-config
devices:
  eth0:
nictype: bridged
parent: lxdbr0
type: nic
  root:
path: /
pool: default
type: disk
name: mycloudinit
used_by: []

and then add it to a profile with:
$ lxc profile create mycloudinit
$ cat version1.profile | lxc profile edit mycloudinit

3. Launch a container while specifying this profile

lxc launch ubuntu:18.04 mycontainer --profile mycloudinit

4. Enter the container and check the cloud-init logs

lxc exec mycontainer -- sudo --user ubuntu --login
cd /var/log/

WHAT ERROR DO YOU GET

ON CONTAINER 18.04, THE ERROR IS:

@Vasiliy: Indeed.

The version in -proposed is "4.15.0-29.31" (source:

The page for that version at

[Bug 1781601] Re: Stress-testing LXD causes kernel hung in cgroups (cgroup_destroy css_killed_work_fn)

[Simos Xenitellis ]

I have been doing stress-testing on LXD at a freshly installed 18.04.
The Linux kernel was the standard 18.04 kernel.
LXD though was compiled from master, ZFS was also compile from master. 

I performed the stress-testing by running the command

lxd-benchmark --count 384 --parallel 24

This launches 384 Ubuntu 16.04 containers in batches of 24 containers.

LXD does not run well on the mainline Linux kernel because I think some 
necessary patches
have not been upstreamed yet. 

I plan to do more stress testing, and when I get the same issue,
I'll run apport to retrieve information from the system to attach here. 
Obviously, when I deploy the server, I'll prepare it for apport beforehand.

This might be related to #1773392.

On the other hand, the issue in #1773392 appears to have been introduced
in more recent kernels (16.04 not affected).

[Bug 1661590] Re: GNOME Software only supports running one application from a snap

[Simos Xenitellis ]

Hi!

On Ubuntu 16.04 (xenial) I enabled the `xenial-proposed` repository and
upgrade `gnome-software`.

$ apt policy gnome-software
gnome-software:
  Installed: 3.20.5-0ubuntu0.16.04.10
  Candidate: 3.20.5-0ubuntu0.16.04.10
  Version table:
 *** 3.20.5-0ubuntu0.16.04.10 400
400 http://archive.ubuntu.com/ubuntu xenial-proposed/main amd64 Packages
100 /var/lib/dpkg/status
 3.20.5-0ubuntu0.16.04.8 500
500 http://archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages
 3.20.1+git20160420.1.ca63436.ubuntu-xenial-0ubuntu2 500
500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages

I launched `gnome-software` and located the `libreoffice` snap package.
I clicked on the Launch button.

WHAT HAPPENED: LibreOffice Base was launched (the wizard for Base to open a 
database).
When I do 'snap info libreoffice', libreoffice.base is the first in the list.

WHAT SHOULD HAPPEN: 
It should launch `libreoffice` instead.

[Bug 1621550] Re: Snappy should detect when running in KVM, specify correct ssh connection line

[Simos Xenitellis ]

The goal of this report is to deal with the usability issue. The issue
that when you start Ubuntu Core through KVM, you do not get a working
command on how to connect to the running image.

A simple solution could be to adapt the text on #1 to say something
like:


    can connect remotely to this device via SSH:
   
   ssh you@10.0.15.1(if running on standalone 
device)
   ssh you@localhost(if running through KVM)


If KVM guests are not expected to be very common, then no change would be 
necessary. Any instructions that describe  how to boot into KVM, should have 
the additional information on how to connect with SSH.

@Timothy:

There would not be much of a need to collect stats specifically from 
motd.ubuntu.com. The user-agent will just say 'curl' in all cases which is not 
that helpful. 
Also, each distro installation checks every day for security updates, so why 
would anyone bother with motd?

There has been a sad Twitter storm in a tea cup over this, and it makes

The script is /etc/update-motd.d/50-motd-news

Obviously there has been an unfortunate mix-up and it shows that HBO-

Is it really necessary to conflate this into some conspiracy to display

[Bug 1681513] Re: Ubuntu 17.04/17.10: New feature in NetworkManager stops several WiFi adapters from working (MAC Address Randomization issue)

[Simos Xenitellis ]

@Marcos:

Thanks for reporting that the same issue exists in current 17.10.
There has been a change in the default settings in NetworkManager in upstream
so that the MAC address randomization is not enabled by default.
Currently, Ubuntu 17.10 (daily) has NetworkManager 1.4.4.
I suppose it will get upgraded to 1.6.2 
(https://wiki.gnome.org/Projects/NetworkManager)
which most probably has the new change.

@aleandro: Most probably something else is wrong with your case. 
If you can connect for a bit and soon you get disconnected, then definitely 
something else is the problem.
Can you file another report for your case?
You can do that by running in a terminal the command: 

ubuntu-bug network-manager

and then follow the instructions.

[Bug 1226962] Re: Hotkeys not functional in non-latin keyboard layout

[Simos Xenitellis ]

** Description changed:

- New keyboard layout changer in Ubuntu 13.10 introduce  old-new bug. Any 
system or application hotkey witch use char (for example: ctrl+alt+t for 
terminal or ctrl+t for new tab in browser) become unfunctional when selected 
non-latin keyboard layout.
- Hotkeys with F1-12, numbers and other non-character buttons works perfectly.
+ Keyboard shortcuts are key combinations like Alt+F (usually opens the
+ File menu) and Ctrl+O (usually opens the File→Open... dialog box).
  
- Window manager hotkeys not affected by this bug. All hotkeys in system
- parameters->keyboard->hotkeys->windows works perfect with any keyboard
- layout.
+ There is an issue with non-latin keyboard layouts that the keys under F or O 
(for Alt+F and Ctrl+O respectively) would correspond to some other character.
+ What should happen then? There is some smart functionality (at least in the 
GTK+ library) that when we press a shortcut, it will try to make Alt+F or 
Ctrl+O work, even if the active keyboard layout is not English.
  
- Workaround for some system hotkeys and two layouts (english and non-
- latin): rebind all hotkeys in your local layout. For example instead of
- ctrl+alt+t use ctrl+alt+τ (greek tau). That hotkey still work with
- english layout.  If you use english and two different non-latin layouts
- this workaround helps only with one of them.
+ For this smart functionality to work, it requires us to have as first 
keyboard layout the English (en) layout. Then, GTK+ will be able to
+ check whether the shortcut makes sense for English, and if so, will run it.
+ All that even if the active layout is Greek or Russian or something else. 
  
+ This report has over 300 comments and these comments include all sort of 
corner cases that indeed shortcuts do not work. In general, shortcuts work,
+ but in specific cases there are issues that need to be fixed.
  
- Dear Ubuntu users and developers! 
- Please include the following information to your comment about non-latin 
shortcuts problems:
- 1. What Ubuntu version do you have (Ubuntu 13.10, Ubuntu 13.10 GNOME, Ubuntu 
14.04, Ubuntu 14.04 GNOME and so on), upgraded (describe version) or clean 
installed
- 2. What keyboard layout do you have
- 3. What shortcut for keyboard layout switching do you use 
- 4. On which session you have problems - that is one from Unity, GNOME Shell, 
GNOME FlashBack/Fallback (Metacity), GNOME FlashBack/Fallback (Compiz)
- 5. With which program and its version and origin (Ubuntu repositories, PPA, 
non-deb binary package from some website) you have problems.
+ What we need to do, is collect those corner cases and create new
+ separate reports.
  
- By providing this information you can make bug-fixing much simpler and
- may be faster.
+ Here are the corner cases:
  
- --
- For other layout switching problems introduced in Ubuntu 13.10 you can see 
bug 1218322.
- --
+ 1. In Dash (in Unity 7), shortcuts like Super+S/W work (for example, Greek, 
Russian), but they do not work for Super+A/F/M/C/V. 
+ Report:

+ 2. Java GUI applications on Linux do not support shortcuts in non-latin 
languages. This is an issue with Java and should be reported there.
+ Java GUI apps are not included in any of the Ubuntu ISOs. 
+ Report: 
+ 
+ 3. Shortcuts that use Ctrl on LibreOffice work for several languages (like 
Greek, Russian), but has been reported not to work on Hebrew.

[Simos Xenitellis ]

@nrbrtx: As noted in #329, the shortcuts for Super+A/F/M/C/V indeed do
not work on Unity.

However, the shortcuts for Super+S/W actually work. This means that the
functionality is there to make Super+A/F/M/C/V work as well. See the
screenshot at #329 that demonstrates that Russian is OK for Super+S/W.

[Simos Xenitellis ]

@dror-sign: I have tested with Ctrl+O (File→Open...). 
Indeed, when they keyboard layout is in Hebrew, Ctrl+O in Libreoffice does not 
work.
However, Ctrl+O in LibreOffice for at least Greek and Russian works.

Therefore, this inability for Ctrl+... shortcuts not working in
LibreOffice for Hebrew is an issue by itself, that is specific to Hebrew
(and needs a new report that is specific to Hebrew and other layouts
that are affected in the same way).

[Bug 1226962] Re: Hotkeys not functional in non-latin keyboard layout

[Simos Xenitellis ]

@dror-sign: I just tried the Alt+F shortcut on LibreOffice, on Ubuntu
16.04, having enabled the Hebrew keyboard layout. It worked for me.

You are supposed to have as primary keyboard layout the English (En)
keyboard layout.

[Bug 1226962] Re: Hotkeys not functional in non-latin keyboard layout

[Simos Xenitellis ]

@xeron-oskom: Indeed, Super+A/F/M/C/V are not adapted and do not currently work 
with Greek either. 
However, what is working, are those shortcuts that I show in my screenshot 
(Super+W, Super+S).

Here is a screenshot that shows that when you switch to Russian keyboard
layout, the Unity shortcuts for Super+W and Super+S are adapted
automatically for Russian.

The way that Super+W and Super+S work, makes me believe that these are not 
hard-coded but dynamic.
Here is relevant code

[Simos Xenitellis ]

@nazar-pc: It is very important to care and make an effort to figure out what 
is going on.
Your case is about Java apps, which is a distinctive group of GUI programs. 
I am not aware of functionality that XIM ('setxkbmap') would offer the feature 
to have working shortcuts with non-English layouts, unless it is some hack that 
is specific to the Java app.

For your case, I highly recommend for you to create a new bug report under 
"java-common",
https://launchpad.net/ubuntu/+source/java-common
with a title like "Shortcuts/hotkeys not working when non-latin layout is 
active",
and describe in detail the problem and add your workaround using "setxkbmap".

Then, post the URL of the report here so that those that are interested, can 
subscribe as well.
I'll then look to find the appropriate upstream project and link there.

[Simos Xenitellis ]

@xeron-oskom: The Unity 7 shortcuts are adapted accordingly when the keyboard 
layout is switched to Greek. See screenshot below. 
When you keep pressed the Win key, you get that information text with all 
shortcuts. 

Admittedly, I just checked that a few shortcuts are not adapted for Greek so 
they require specific bug reports. However, the general functionality is there.
Can you check what is shown in my screenshot, but for Russian?

This bug report has reached 325 comments. Any developer would struggle
to make sense as it is now.

[Bug 1226962] Re: Hotkeys not functional in non-latin keyboard layout

[Simos Xenitellis ]

@nazar-pc: Java GUI apps on Linux is a special case. Firstly, they are
no such apps pre-installed, so it is somewhat a non-Ubuntu problem.

Gedit is written in the C programming language and is part of the core
GNOME apps. It is well-support and shortcuts work. It has been working
for 10+ years, since the multi-layout shortcut support was added to
GTK+.

This ability to use shortcuts even when the active layout was not
English, was added to GTK+ (GNOME) at around 2005, perhaps earlier. It
was the first UI toolkit to have such support for shortcuts when the
active layout was not English. Qt did not have it for a long long time
(has it been added there?).

I am inclined to close this report in a few days if we do not get a 
reproducible case of shortcuts not working.
At the same time, I'll open (if they do not exist) individual reports regarding 
shortcuts in Java GUI apps and other toolkits that do not have that support.

[Bug 1226962] Re: Hotkeys not functional in non-latin keyboard layout

[Simos Xenitellis ]

I think this report needs to clear up. The title and the description
should get an update.

I am using stock Ubuntu 16.04.2 (i.e. Unity 7) and I have configured two
keyboard layouts, EN, GR.

I start gedit and I press the Ctrl+S (Save) hotkey. 
In both cases (Layouts: EN (English), GR (Greek)), the Save dialog box appears.
Similarly, I tested with Firefox, Chrome and Chromium and it worked as well 
(Ctrl+τ to open a new tab).

Therefore, it is working for me at least for these apps.

Is there anyone that cannot get this to work on Ubuntu 16.04?
If so, tell me what keyboard layouts you have enabled. 
Note that the first keyboard layout MUST be "En" (English).

[Bug 1681513] Re: Ubuntu 17.04: New privacy feature in NetworkManager stops some WiFi adapters from working (mac address randomization)

[Simos Xenitellis ]

@Don Cady:

The source of the problem is the Linux kernel driver for the specific
WiFi adapter or perhaps the firmware of the WiFi adapter.

In most of the drivers, they have implemented the facility to change (by 
software) the MAC address.
There are even tools to change the MAC address, like "macchanger". Or, you can 
even use "ifconfig wlan0 hw ether 00:11:22:33:44:55". Or, you can change it 
with NetworkManager, a facility available for many years already.

A WiFi card can support many other interesting features, including "AP
Mode" (make your Ubuntu act like an Access Point), and "Monitor" mode
(using those Aircrack tools). However, it takes effort to reverse-
engineer AP Mode or Monitor mode, so many adapters do not support these
features. It is much more common in USB adapters not to have full
support for these features, and in some cases it is a deficiency in the
firmware (firmware files: /lib/firmware/, and nothing can be done about
it).

It is not clear how widespread is the problem. If you are reporting,
please include which kernel driver is used for the WiFi and also what
firmware is loaded.

@wolfy1339:
I think the MS Surface Pro has an (internal) USB WiFi card and uses the kernel 
driver "mwifiex_usb". Have a look in "lsmod".

[Bug 1681513] Re: Ubuntu 17.04: New privacy feature in NetworkManager stops some USB WiFi adapters from working (mac address randomization)

[Simos Xenitellis ]

Jesse, I do not have 17.04 so I cannot test these myself. You guys could
help:

At https://blogs.gnome.org/thaller/2016/08/26/mac-address-spoofing-in-
networkmanager-1-4-0/ it mentions that:

Update-2017-01-25: with 1.6 release and newer, the default value changed
from “permanent” to “preserve” [commit],[bug].

The "preserve" default value means that NM will not attempt to change the MAC 
address upon activation. 
I just checked the source of "network-manager" on 17.04 (using LXD with 17.04 
container) and it goes not have this update.

Could you please check in NetworkManager to see what is the default value for
“ethernet.cloned-mac-address” and “wifi.cloned-mac-address”, on a Ubuntu 17.04 
installation?

I think that "nmcli device show" might show it. If not, try somehow to
figure out the default.

** Description changed:

+ According to 
+ 
https://blogs.gnome.org/thaller/2016/08/26/mac-address-spoofing-in-networkmanager-1-4-0/
+ there is a new privacy feature in the new version of NetworkManager.
+ This privacy feature can cause some USB WiFi adapters to stop working
+ while they used to work with older versions of NetworkManager (Ubuntu 16.10 
or older).
+ 
+ The purpose of this privacy feature is to get your computer to report a new 
random MAC address whenever you connect to a WiFi network.
+ This privacy feature is especially useful when you connect to public WiFi 
networks, so that the operators cannot identify you when you connect multiple 
times.
+ 
+ The downside of this privacy feature is that some USB WiFi adapters misbehave 
when NetworkManager tries to change their MAC address repeatedly. 
+ The result is that those USB WiFi adapters cannot connect anymore to the WiFi 
 network.
+ 
+ Original report follows:
+ 
  My Panda USB wi-fi adapter works just fine on 16.10, but when I try to
  connect to my wi-fi router in 17.04, GNOME network manager reports
  "Connection failed." I did some tinkering, and noticed that my MAC
  address for my wifi adapter, according to GNOME, is DIFFERENT every time
  I make it forget my wifi settings and try to reconnect. Weird, right?
  Any leads on a possible fix or work-around?
  
  I'm running the latest beta of Ubuntu GNOME 17.04, kernel
  4.10.0-19-generic, GNOME 3.24.0.

[Bug 1661590] Re: GNOME Software only supports running one application from a snap

[Simos Xenitellis ]

A note here that when you run "snap info libreoffice", the order of the
commands actually changes every time you run it. I suppose that snapd
does not have the order of the commands as given in snapcraft.yaml.
That's what I get with snap 2.12

A workaround could be for Ubuntu Software to pick the shorter filename
(for LibreOffice, that would be "libreoffice", the wizard, which is what
is expected to run).

[Bug 1655641] [NEW] Should be able to also search and install fonts, not only apps

[Simos Xenitellis ]

Public bug reported:

GNOME Software can only search and install packages which are (probably) marked 
as GUI applications.
In terms of usability, it is a good choice and the chances to mess up a system 
are diminished.

As a result, it is not possible to install fonts.
Fonts should also be regarded as packages that can be searched for and 
installed through GNOME Software.

Reproduce: 
1. Start GNOME Software
2. Search for "font"

Expected result: several packages about fonts should be shown
What happened: no packages are found

[Bug 1584234] Re: mysql-server fails to install if it cannot start due to not enough memory

[Simos Xenitellis ]

I had a look at the other bug report.

I think the significance in this report is that the mysql-server package
can fail to install altogether (if the installation misjudges how much
memory to assign to mysql), requiring the administrator to use package
management commands in order to fix.

I got this problem when trying out Juju on the LXD provider. 
The server had 2GB RAM, shared among the containers. 
The installed mysql-server package got (auto?)configured to allocate 1.6GB of 
memory, thus failing to start, and failing to complete the installation. This 
is my recollection of what happened.
I had a look at the packaging of "mysql-server" and did not see any 
"autoconfiguration" for the memory. Therefore, it might just be Juju that 
configured the 1.6GB.
I'll try again to install Juju and get a better picture of what is happening.

[Bug 1591124] [NEW] LXC: Cannot create a container with the specific alias "tasks"

[Simos Xenitellis ]

Public bug reported:

When trying to launch a container with the specific alias "tasks", it
fails to launch.

$ lxc launch d23ee1f4fd28 tasks

directory that has as a name the alias that we have given.
Since "tasks" is reserved", lxc fails to continue.

[Bug 1584234] [NEW] mysql-server fails to install if it cannot start due to not enough memory

[Simos Xenitellis ]

Public bug reported:

The default installation of mysql-server is completed successfully if it
manages to start at the same time. If for some reason mysql-server
cannot start, then the installation fails without giving a comprehensive
error message. The user has no clue as to why the installation failed.
The only file with information is /var/log/mysql/error.log.

Users run Ubuntu on affordable servers with little memory (Amazon EC2 600MB 
RAM, or DigitalOcean 512MB RAM). In addition, users may use containers like LXD 
which means that mysql-server may not get as much memory as required. 
Therefore, the installation may or may not fail. In addition, mysql-server may 
crash latter if not enough memory is available.
The default requirement for memory for mysql-server is 128MB (InnoDB).

There should be a way to inform the user that mysql-server does not
install if there is not enough memory.

Attempt for installation of mysql-server, which fails due to not enough memory. 
The messages do not give a clue that the problem is memory-related. 

The commands (systemctl, journalctl) that are mentioned, do not provide

The problem is that the installation of the mysql-server package requires a 
successful launch of the MySQL server. If MySQL cannot start, then the package 
is not fully installed.

I got the exact same issue.

This is about installing "mysql-server" on a pristine Ubuntu 16.04 on 
DigitalOcean.
The installation fails.

[Bug 1512993] Re: VLC exhibits blockiness on h264 seeking

[Simos Xenitellis]

It looks like an issue specific to this class of videos. 
Whether a video file is .avi or .mp4, it can have the audio/video compressed in 
different ways.
Since the test video is 190MB, you can post the video details. Install _ffmpeg_ 
and run _ffmpeg -i myvideo.avi_. 

Here is the output:

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Day 2-2016-01-27 20.31 Core Spring 
Training.mp4':

(default)
Metadata:
  handler_name: Citrix h264 stream handler
  encoder : AVC Coding

Here it says that the audio is compressed with AAC (VLC is fine with
that) and the video is compressed with h.264 (by an encoder created by
Citrix).

VLC (VLC media player 2.2.1 Terry Pratchett (Weatherwax) (revision
2.2.1-0-ga425c42)) did not work either for me; the audio was fine but no
video.

I was able to play the video with mplayer2 (command line player,
MPlayer2 2.0-728-g2c378c7-4build1 (C) 2000-2012 MPlayer Team) and ffplay
(command line player, ffplay version 2.7.6-0ubuntu0.15.10.1 Copyright
(c) 2003-2016 the FFmpeg developers). Both audio and video worked.

In addition, I managed to play the video in Totem (Ubuntu 15.10). Totem
is based on gstreamer, so gstreamer is also fine.

Therefore, the problem is likely to be with VLC and not the graphic drivers.
If you disable _Accelerated video output_ in VLC, the video still does not play 
(audio is fine, but no output; just black).

[Bug 1512993] Re: VLC exhibits blockiness on h264 seeking

[Simos Xenitellis]

Summary: the default video player in Ubuntu is Videos (the app "totem")
and it can play this video just fine.

Still, it would be great if the problem in VLC gets fixed. VLC uses its own 
audio/video decoding software. 
Videos (Totem) uses "gstreamer" and it works. Mplayer2 and ffplay use something 
based on ffmpeg and they work as well.

[Bug 1506562] Re: Ubuntu 15.10 Beta 2 fonts change after reboot

[Simos Xenitellis]

I just installed freshly Ubuntu 15.10 using the Greek locale.
I did not make any changes to the settings. 

Indeed, the fonts look terrible and different from previous versions of Ubuntu. 
The reason is that, instead of showing the Ubuntu font family, the Dejavu font 
family is shown by default.
Something has changed that makes Ubuntu 15.10 to show Dejavu instead of the 
Ubuntu font.

[Bug 1447256] Re: "Force UEFI" dialog displayed if user selects custom partitioning

[Simos Xenitellis]

Workaround #1: 
Create partition table using "gparted". 
Create one 200MB partition with filesystem FAT32. Then click Appy so that 
"gparted" applies the change.
Then, change the flag of the partition (right-click on partition, then Manage 
Flags) in order to add the "efi" flag.
Save and exit. 
It should be possible to using the installer (ubiquity) and complete the 
installation.

Workaround #2: 
Do not use the "Something else" option in the installer.

I am installing Ubuntu 15.10 (final) and I encountered this issue (exactly as 
described by the original poster).
This issue is mentioned in https://wiki.ubuntu.com/WilyWerewolf/ReleaseNotes as 
well, in the Known Issues section.

However, in my case the Force UEFI dialog cannot be closed, thus, it is
not possible to continue the installation.

See http://www.whizzy.org/2015/09/big-bug-bonanza-16-04-lts/ for a sprint

Since there are patches for this and these patches work, it is important to
get the issue fixed during the sprint.

[Bug 1465959] [NEW] In phones with two SIMs, if you don't unlock SIM1, the message for unlocking SIM2 says SIM1

[Simos Xenitellis]

Public bug reported:

How to reproduce:

1. Use a dual-SIM phone (tested on bq Aquaris E4.5) with two SIMs, both SIMs 
should require a PIN to unlock.
2. When booting the phone and prompted for SIM1 PIN, click on X in order not 
to provide a PIN (thus SIM1 will remain locked).
3.
WHAT YOU GET: 
The message says Input PIN for SIM1 even if this is the turn for SIM2 to 
input the PIN.

WHAT SHOULD HAVE HAPPENED:
The message should say Input PIN for SIM2 instead, since now we are typing 
the PIN for SIM2.

(I am using a localised build, so the text in the message may not be
exact.)

[Bug 1464159] Re: Web browser should send the system language to websites (Accept-Language field)

[Simos Xenitellis]

** Tags added: i18n

** Description changed:

- I created a webapp for the secure email service Tutanota.  One nice
- feature is that it is localized in several different lanaguages and it
- automatically presents its interface in the user's preferred language.
+ When the user has selected a specific system language for the phone,
+ the Accept-Language HTTP header field should be set to that language.
+ 
+ Currently, Accept-Language is hardcoded to en-us;en;q=0.8.
+ 
+ To test:
+ 
+ 1. [In the phone] Go to System → Language and Text → System Language
+ Select something other than English (United States).
+ 
+ 2. To check the Accept-Language value, visit a website like
+ http://myhttp.info
+ 
+ WHAT HAPPENS NOW:
+ Currently, Accept-Language is hardcoded to en-us;en;q=0.8. 
+ 
+ WHAT SHOULD HAPPEN: 
+ The Accept-Language HTTP field should reference the system language (for 
example, for Greek, it should say something like el;en-us;en;q=0.8.

+ 
+ ---
+ I created a webapp for the secure email service Tutanota.  One nice feature

  Unfortunately, the Ubuntu browser does not present the Accept-Language
  header and Tutanota does not offer language as a settings option.
  
  I think it would be optimal if the browser uses the system language as
  the Accept-Language header (and would be awesome if it used the active
  keyboard layout options to create a list of additional languages), and
  of course even better if the browser settings page also allowed
  customization as well.

[Bug 1445358] Re: Pulseaudio fails to run when system's language is in Greek

[Simos Xenitellis]

The relevant message in /var/log/syslog is:

Apr 20 14:03:45 user-laptop pulseaudio[1661]: [pulseaudio] module.c:
Failed to load module module-alsa-card (argument: device_id=0 name

What is says here is that insmod (or similar) was called with
parameters like tsched=ναι, and failed.

git blame says:

which means that about a year ago a change was made to make yes/no

A quick fix is to make pa_yes_no() non-localisable again.

[Bug 1271268] Re: 174c:5106 1 TB External USB 3.0 Drive Fails to Automount through USB 3.0 dock with XHCI Enabled

[Simos Xenitellis]

Apparently this is a regression in the xhci code (USB3). If you connect
the device to a USB2 port (if you have one) or disable xHCI in the BIOS,
the problem is gone. Of course you get USB2 speeds as well.

Relevant bug reports:

Bug#741989: linux: 3.13.5: known regression: xHCI xhci_drop_endpoint called

In a nutshell, 
1. when something goes bad, the first dmesg messages say

disabled ep 8801de04f6c0
(probably multiple times if keep using the drive)

2. Then, the drive is disconnected and reconnected again. If you have
the default setting to automount, you get many Nautilus windows opening
up.

[Bug 1244548] Re: Keyboard shortcut for changing keyboard layout does not work on lock screen

[Simos Xenitellis]

@minniegaliev-r: It comes out as obnoxious to post a comment like Why 
importance only medium?. 
It should have been a complete statement as in: 

I think the importance for this report should be raised to High. The
reason is that if you get locked out in the screensaver while your
current keyboard layout is not English, then you are stuck badly. If you
do not have a mouse to click-switch to English, you have no other option
than to hard-reboot your computer ;-'( This is a big issue.

[Bug 1226962] Re: Hotkeys not functional in non-latin keyboard layout in 13.10

[Simos Xenitellis]

A bit of essential fact-checking:

X.Org/XKB consider different the shortcuts like Ctrl+T (latin t) and
Ctrl+Τ (greek τ) and so on. Because they are different characters.
Obviously.

It is because of gtk+ (with gtk+ input method) that shortcuts like
Ctrl+Τ (greek τ) work just like Ctrl+T (latin t). This has been really
amazing and usable, and we all like it. It's a gtk+ feature (if you use
the gtk+ input method), and when we move to different toolkits/input
methods, we need to make an effort to replicate the functionality.

Apart from an amazing feature, it is also a hack. It makes a mess to
those that use unconventional layouts like dvorak. Ok, those are a
minority compared to us...

In this report, the source of the issue is either not using the gtk+
input method in gtk+ apps, or non-gtk+ apps (which obviously do not use
the gtk+ input method). Also, there might be cases (I am speculating)
that keyboard filtering might mess up as well.

If you want to figure out whether the gtk+ input method is actually
working, you can type Ctrl+Shift+u (latin 'u'), then type aa and then
press spacebar. If you get ª, then the gtk+ input method is working for
you.

[Simos Xenitellis]

I am running 13.10 with all updates applied. I have enabled English and Greek.
The LibreOffice shortcuts such as Alt+F (File menu) does not work either for 
English, neither for Greek.

Can someone verify whether the shortcuts work for English in LibreOffice?
Because if they do not work in English either, then the problem is wider.

(if someone has enable just a single keyboard layout, does that make a
difference?)

I also want to add https://bugs.freedesktop.org/show_bug.cgi?id=60126 to
this report but cannot figure it out. If someone can figure it out,
please add it.

From a comment above: 
The problem with both the LibreOffice and Latex generated PDF files seems to be
that they have a very small or zero volume /Rect field. The annotations in the
attached test case are in fact there. There is a very small area where hovering
the mouse shows the first comment.

Additionally, the annotations do not contain a /Popup field, which means
clicking them does nothing.

[Bug 1226962] Re: Hotkeys not functional in non-latin keyboard layout

[Simos Xenitellis]

@Artyom: The issue is with Ubuntu 13.10 which has specific new changes when 
switching layouts.
My layouts are EN/GR/RU, and while RU is active, the shortcuts do not work. I 
tested with Ctrl+A (Select All).
Do note that I check with 'gedit' (core GTK+ app). Some other apps like 
Chromium have specific changes and are unaffected.

@Misha: So you are saying that the bug still exists, it is not a Unity
bug, but solely an indicator keyboard bug.

[Bug 1226962] Re: Hotkeys not functional in non-latin keyboard layout

[Simos Xenitellis]

@Stephen: In Greek, the Z key happens to be on the same physical key as Z
on the US English/British physical key (Qwerty).

@Lars: GTK+ has code in
https://git.gnome.org/browse/gtk+/tree/gtk/gtkkeyhash.c so that when you
press Ctrl+A (where A is the Greek A), it will search what was supposed to
have been pressed if the first group (let's say 'keyboard layout', commonly
US English) was active. Thus, Ctrl+A (Greek Alpha) works with the GTK+ IM.

There is an issue if you happen to have two Latin keyboard layouts, such as
US English + German. Such a difficult situation is discussed at
https://bugzilla.gnome.org/show_bug.cgi?id=162726.

I think the goal for 13.10 should definitely be to get the GTK+ IM
functionality working again.

 A Greek keyboard does not have a physical Z key, nether does an Arabic
 or Hebrew keyboard.   There are different requirements for Latin and
 non-Latin keyboards, and different requirements again for IMs like the
 various Indic or CJK entry systems.  That's why it's definitely wrong to
 force ibus to run when it's explicitly configured not to.

 Bug description:
   New keyboard layout changer in Ubuntu 13.10 introduce  old-new bug. Any
 system or application hotkey witch use char (for example: ctrl+alt+t for
 terminal or ctrl+t for new tab in browser) become unfunctional when
 selected non-latin keyboard layout.
   Hotkeys with F1-12, numbers and other non-character buttons works
 perfectly.

   Window manager hotkeys not affected by this bug. All hotkeys in system
   parameters-keyboard-hotkeys-windows works perfect with any keyboard
   layout.

   Workaround for some system hotkeys and two layouts (english and non-
   latin): rebind all hotkeys in your local layout. For example instead
   of ctrl+alt+t use ctrl+alt+τ (greek tau). That hotkey still work with
   english layout.  If you use english and two different non-latin
   layouts this workaround helps only with one of them.

[Bug 1226962] Re: Hotkeys not functional in non-latin keyboard layout

[Simos Xenitellis]

I am using 13.10 (latest updates) and I have configured the layouts US
English, Greek, Russian.

I started gedit (core GTK+ app) and I switch keyboard layout to Greek.

1. I typed some text in Greek. Then, pressed Ctrl+A (Select All) but nothing 
happened. Instead, the whole text should have been selected. 
In the Greek keyboard layout, the Greek A is on the same physical key as the 
Latin A. 

2. I pressed Alt+F (Open the File menu). Nothing happened.


GTK+ should have handled correctly both of these cases as it has code to handle 
the multiple-layout issue.
I tried to unset 'GTK_MODULES' (has a value of 'unity-gtk-module'), but I did 
not get back the old behavior. 
I could not find a workaround for these critical issues.

[Bug 1226962] Re: Hotkeys not functional in non-latin keyboard layout

[Simos Xenitellis]

A workaround to get shortcuts in non-Latin scripts to work again is to
kill any IBus processes.

I killed

/usr/bin/ibus-daemon --replace --xim --panel disable
/usr/lib/ibus/ibus-dconf
/usr/lib/ibus/ibus-x11 --kill-daemon
/usr/lib/ibus/ibus-engine-simple

and then I could Select All, or start Alt+F to get the File menu.

Thus, IBus is interfering with GTK+ apps, even if for those apps the
default GTK+ IM is active.

[Bug 1205713] Re: unable to type Greek characters to the dash

[Simos Xenitellis]

@BrandonSchaefer: Could you please have a look at 
https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1228422

I think we got major regressions from this change. 
In a nutshell, IBus does not support features that we have been used to, when 
we were using the GTK+ IM. For example, accelerators and menu shortcuts do not 
work anymore.

Is it possible to get IBus enabled only when the app that has the focus
is Unity?

[Bug 1228422] [NEW] Severe regressions to typing in Greek, Russian, etc due to IBus

[Simos Xenitellis]

Public bug reported:

For the last several versions of Ubuntu, there was an inability to type Greek 
(or many non-latin scripts) in the Dash.
With bug https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1205713 the 
problem has been fixed, and it got fixed by enabling IBus for Greek, Russian 
and several other scripts. 

However, this change revealed several deficiencies in IBus (tested with
Greek and Russian):

1. It is no longer possible to use keyboard accelerators when the active 
keyboard layout is in Greek, Russian, etc. 
The reason is because the gtk+ IM contains special code so that Ctrl+A while in 
the Greek keyboard layout would still do a Select All.
Currently in Ubuntu 13.10, when you press, for example, Ctrl+A (with Greek 
layout active), the app receives a Greek Alpha, which is ignored by the app.

The same goes with, for example, Alt+F, which no longer opens up the
File menu.

More background about this at 
https://bugzilla.mozilla.org/show_bug.cgi?id=69230#c2
(FIXME: need to add link to gtk+ git with code on how they implement the 
solution)

2. The default keyboard shortcut to switch between keyboard layouts is
Super+Space (default for IBus). Pressing the Super key ends up bringing
up the HUD most of the times. I have been trying to get myself to press
Super+Space more properly, but it's really difficult to get it right. I
now get it right only about 30% of the times, and I need to pause when
typing in order to check if I am actually writing by accident in the
HUD.

I would say it is a huge usability issue that, as is, will alienate non-
English users of Ubuntu.

3. It is not possible to change the shortcut to switch keyboard layouts to the 
traditional Alt+Shift (used by most Ubuntu-gr users). 
In addition, if you manage to change the shortcut to something else, then it's 
impossible to change back to Super+Space.

[Bug 1205713] Re: unable to type Greek characters to the dash

[Simos Xenitellis]

I am also affected by this; using Ubuntu 13.10 with en_US.UTF-8 locale,
and unable to type Greek.

Can you see at all the Greek localisation of Unity in 13.10; A Russian 
translator mentioned that the Russian translation is not visible either. A 
quick explanation would be if Unity runs under the C locale, which is not a 
Unicode locale.
If the only characters that can be typed are from ASCII 
(http://www.asciitable.com/ - NOT extended), then most probably it is a locale 
issue not supporting the UTF-8 encoding.
