Hellow Tom!

I did mean that 10 years of security updates.
Most Ubuntu users know this news, i think.

You can remove the dkms-built modules for specific kernel versions.  See

I can't interpret what this 10 year advantage refers to. Could you expand on

Aha. Just a random test (Debian Bullseye here, so not the newest):

  tomas@trotzki:~$ bash --version

This page says that bash 5.1 is 2020-12-07. So Ubuntu 22.10 would be

Your description is too general, it lacks details. E.g. you did not 
provide exact commands and their output that you use to check that 
defaults are set properly.



This happens in both Chrome and Firefox.


Open web development tools, switch to the network tab, click on the 
link, check MIME type in server response headers.


In Firefox check application associations in preferences (settings).

If you save link target to disk, can you open the downloaded file by 
thunderbird directly and by xdg-open? What is MIME type reported by the 
"file" utility?



I am running Debian 10/Buster with all of the latest updates.


Behavior might depend on your desktop environment.


The following files have been updated to point to Thunderbird:

~/.config/mimeapps.list


It is hard to reason whether it should work without details what you 
have added to this file.


Check entries related to evolution in this file and MIME types specified 
in its .desktop file.

Ubuntu more quickly upgrades to fresh versions and have longer lts
support, in Debian i'm get more expectable results.

I tried _minimal_ installation option of ubuntu server 22.04 iso and
it not so minimal as in debian — about 6G on disk with unexpected soft
in memory. After that — use only debootstrap when installing ubuntu.
Two docker servers, debootstrapped same manner works identically.

I have experience both Ubuntu and Debian. Google cloud vm is running
Ubuntu 18.04 LTS (+ESM). Then my desktop is Debian 11 under Chromebook.

Ubuntu's advantage is 10 years.

So i prefer Ubuntu LTS for cloud/server.

Just so so

Unable to open Thunderbird as default calendar app

[John Boxall]

I am trying to launch Thunderbird as my calendar application when 
opening a webcal link. Though I have updated all appropriate 
gnome-mimeapps.list and mimeapps.list files and used xdg-mime to query 
and set the default calendar application, my user session wants to open 
Evolution. The GNOME defaults for mail and calendar were already set to 
Thunderbird. If I remove Evolution, the dialog opens but specifies 
xdg-open and there are no options to choose another application.


This happens in both Chrome and Firefox.

I am running Debian 10/Buster with all of the latest updates.

The following files have been updated to point to Thunderbird:

~/.config/gnome-mimeapps.list
~/.config/mimeapps.list
/etc/xdg/gnome-mimeapps.list
/etc/xdg/mimeapps.list
~/.local/share/applications/gnome-mimeapps.list
~/.local/share/applications/mimeapps.list
/usr/local/share/applications/gnome-mimeapps.list
/usr/local/share/applications/mimeapps.list
/usr/share/applications/gnome-mimeapps.list
/usr/share/applications/mimeapps.list

I would appreciate if someone could point me to the missing puzzle piece.

Uit `man 1 ssh`

Ik had gedacht om het dicht te timmeren door aan authorized_keys

het account dat de `ssh -N` moet gaan doen.

Er is "no-port-forwarding"

Wat zien jullie zoal aan mogelijkheden om aan server kant
er voor te zorgen dat SSH client alleen maar een verbinding
voor de portforward maakt, dat shell access niet kan?


Wat ik doe aan de server-kant is /usr/sbin/nologin als shell gebruiken.


Oh, en ik zie dat ik ook dit nog doe in sshd_config:
-
UsePAM no
Match User een,twee
   AllowTcpForwarding remote
   AllowStreamLocalForwarding no
   X11Forwarding no
   PermitTTY no
   PermitEmptyPasswords yes

Dat aandacht op "alleen maar een verbinding voor portforward" blijft.


Oorspronkelijke vraag heb ik kunnen oplossen door


command="echo Don\'t do that"

voor de pubkey in ~/.ssh/authorized_keys te zetten. Dat is aan server
kant.

Als ik `ssh -N -R :127.0.0.1:22 server` doe, krijg ik de gewenste
portforward. Als ik iets zonder `-N` doe, komt er "Don't do that" terug.


Waarom geen shell die alles weigert?


Ik heb trouwens nog een kleine extra beveiliging in de firewall, mensen
moeten zich eerst ergens aanmelden, dan pas krijgt hun IP toegang.


Met behulp van   from="hun IP"   voor de pubkey in authorized_keys?


Ze moeten eerst ergens naar een webpagina gaan, die triggert een script 
wat de firewall openzet voor hun IP voor een dag. Normaal staat die 
firewall dicht.


Ze kunnen "inloggen" zonder key en zonder paswoord, maar krijgen dus 
"nologin" als prompt. Het is alleen bedoeld voor portforward, via die 
portforward kan ik op hun machine komen voor support.

Re: gradle wants openjdk-11 even if a newer version is installed? ...

 Let me try to disabuse myself somewhat with a bit of humor. Some of
you have been telling me for a long time about how "visually
upsetting" and "procedurally obnoxious" I am and as they say:
"misunderstanding is as mutual as love should be". I can't really make
sense of what you are telling me, nor do I understand why you would
even take the time, energy to do so. Becoming a teacher, taught me to
be a better person and notice a lot of other things about "people" (as
a teacher you must entertain the functional illusion that people can,
do learn, have free will, ... in the same way that when you are a
doctor you must understand that there is an essential difference
between biological beings, rocks and the rain). Now, do you know that
more than a generation ago handwriting was basically written off
curricula in the U.S.!

 
https://www.theatlantic.com/magazine/archive/2022/10/gen-z-handwriting-teaching-cursive-history/671246/

 I have a hard time even trying to figured out what my students' name
(let alone what they had written), but I would not really care about
the visual aspects of it I would just try to decypher it. The same
problem I have had with the truly crappy code that I have had to debug
and here when I say "crappy" I am not referring to the visual
impression of it (some people tend to make a big deal about the number

the new normal being taught is keyboarding.
~
 Partially due to habituation, the neurobiology of our perception,
evolutive adaptations, culture, ... we all have our own ways of doing,
liking and disliking things. I am not a visual person, nor is my
brother and mother (both excellent, creative musicians) and there is
"something it is like" not being a visual person. I asked once my
supervisor: "why she was talking in a bossy way to me and why she was
talking like (with the timbre, voice and accent of) my supervisor?".
You walk into a crowded elevator and you overhear two people talking,
your mind goes "I know these 'voices'" and when you turn in an
inadvertent way they happily go like: "Hi, Mr. López! How are you?"
and I put on a smirk while "my mind" goes like: "and who the eff are
you guys?" As girlfriend has told me "I can't just sit and watch a
movie with her". I don't even own a TV set. The idea of "'just'
sitting to watch a movie" I find so out of it all stupid that when
girlfriend has forced me to go to the movies with her (and who am I to
think that I don't have to do what my lady says?!) I invariably go
with my books and almost always have stepped out to the lobby to read
as I wait for her to come out. There are only like five (5) movies I
can watch, have kept watching. I was shocked, very confused when I
have heard Žižek using movies for his elucidations. I had put up with
his philosophical bitchiness because we both love grandpa Hegel, but
that started to give me serious doubts about his smarts and the depths
his mind could reach.

 I keep three languages (all of them shamefully enough European), but
even the white space doesn't feel the same in German, English or
Spanish, not even within the same paragraph in the same language (I
have heard other people saying similar things). They somehow feel like
tones within their melodies. Racism (another "visual thing", mind you)
I can't make sense of (I have a very hard time visually telling people
apart, which the police know, so they use it against me). I take it as
"a necessary social, 'functional illusion'", that people choose, need
to believe in to make sense of, "justify" other social needs; kind of
the crazy obsession Nazis/Adolf Hitler had with people's ears. He sent
his "personal photographer" to a meeting some Nazi officers had with
the Soviet nomenclature with the special job to get a good picture of
Stalin's ear, to see "if he was really human", which based on his ear
lobes he was! (what a disappointment!; now, that story is not totally
stupid and hopelessly so, at least there was a falsifiable way to
check your assertions. To gringos Russian people are "un-'American'"
anyway (and in addition to that they are pro Russian?!) and that is
all they need to know, they wouldn't have to prove anything to
themselves). I once read from a scientific report from the times
before the wide spread adoption of the Internet, computers and cell
phones that on average gringos spent (1/4) of the waking time of their
life watching TV! How is that even possible, even Mathematically! and
the funny thing about it is that they make fun of Muslim people going
for their relatively brief prayer calls three times during the day. Do
the Math! I would rather pray to "Vladimir Putin" if it came to that,
than spending (1/4) of my waking life watching TV!

[Bookworm] installer stops due to missing wifi firmware

[Ismael Farfán]

Hello

I'm trying to install Bookworm on a G513QY laptop with MT7921 wifi adapter.

As soon as the installer (Net or DVD) tries to detect the HW, the installer
stops blank.

The last thing I see in dmesg is something like
Detected ethernet HW, renamed to eth0 (succeed)
then... :
Failed to load mt7821 firmware (lots of this)
hardware init failed
[ loaded modules]
[ stack trace ]

rfkill
wiphy
ieee802


Any ideas or workaround for this?

I also tried with the advanced installer from the DVD but it always wants
to try detecting the network HW and stops there.

I believe you've mistyped the number, and actually mean 14755, unless
my Google-fu is extremely bad.

In any case, this is clearly implemented at the terminal (or other GUI
app) level, not at the text editor level.  So it "works" in vim for
you, because you're running vim in a terminal which supports this
feature.  And it "doesn't work" in vim for me in xterm, because xterm
doesn't support it.

 also suggests Ctrl+Shift
as the "beginning key sequence", but this is clearly just meant as one
possible implementation choice.

It's lxterminal, not lxterm, and it's part of LXDE so I'm surprised if
it's bundled with xterm.

It seems to be a somewhat complex thing. It might be invoked by ibus,
apparently, but I don't have that installed. I don't know what all the
possibilities are for enabling or disabling the facility. You can see
it described at
https://en.wikipedia.org/wiki/Table_of_keyboard_shortcuts under the
heading of Insert Unicode for linux. There's no qualification there,
unfortunately.

It works here in both vim (the terminal-based editor) and gvim (the
identically-functioned separate window-based version). Hitting space
instead of enter causes it to erase everything back to and including
the CTRL-SHIFT-U.

The mechanism is specified by the standard ISO 41755, but it doesn't
specify the introducer sequence. I have no idea how it is enabled or
disabled.

I use xli to view images. I like it primarily because it requires no mouse.

It also has a lot of command line options that I don't understand, but

more legible


  $ xli -colors 2 MKS_Robin_Nano_V3_PIN.png # Only ONE shade of gray

Re: Which takes priority, ipv4, or ipv6?

I'm not adding anything new here, only pulling together what has
already been said in several different replies.

There are three main places where this can be affected.

Firstly the DNS servers you use can decide on their own what to
return to you. Normally it's expected that a resolver is going to
return everything that is in the DNS zone for the query you made,
but some DNS servers (both authoritative and resolver) do decide to
give you filtered results which may for example exclude 
records. No  records, no possibility of an IPv6 connection.

Secondly, your application that gets a list of answers (A and 
records) might do something special. It is after all free to do
whatever it is programmed to do. The most common example of this is
"Happy Eyeballs", where (simply put) web browsers connect to BOTH A
and  and use whichever works first.

Thirdly, if no special handling is in use then your operating
system chooses which address to use. There's an RFC for that, and
all of that is configured in /etc/gai.conf on Debian. The default
behaviour is to try IPv6 first.

So, DNS tools like "host" will not answer this question for you
because that is only showing you the first part. That's enough to
show you what your options are, but your app might use those options
in a way you weren't expecting. Some apps might not even support
IPv6. For most apps /etc/gai.conf controls this.

You mentioned in another email that you had to alter gai.conf to
make IPv6 be preferred. That is unusual as it is not the expected
default behaviour.

Cheers,
Andy

 "random things" you said?

 Since we are talking here about gradle which is based of groovy,
which is just a DSL implementation in java exploiting its reflection
API, ... you are not making much sense. Notice that on their
installation page:

 https://gradle.org/install/

 they are not telling you that you must have exactly jdk-11. They do
state that it must be greater than java version "1.8.0_121" which you
check in exactly the way I did; so, it seems that during installation
they do check for a java installation in the standard "java -version"
way.

 What I am talking about doesn't exactly relate to what "package
managers" do, or so I thought.

If they are actually PNGs you'll be out of luck with esc sequences.
You might get away by fumbling the image's palette (if it has one)
or postprocessing it with your favourite image manipulation program
(with enough dedication you even might come up with some ImageMagick
script to automate this).


Begs the question, do we have a gfx editor that can do that? Fix it once, at
the src. I'd be in hog heaven!


You mean at Alibaba? Or in your copies of the images?

In my copies stored here, alibaba likely has a reason for their choice, 
made no doubt by the 7 figure legal people.  Cheating on the gpl while 
appearing to meet the terms.



In the second case, I'd recommend Gimp if you are more
the clickey type or the ImageMagick suite (specifically
convert) if you are up to figuring out a script which
might do it automatically for you henceforth.

That would be a likeable, usable solution.  As for gimp, I use it mainly 
to squeeze pix, making a 20 meg pix out of my canon camera into 
something I can email at sub 300k.  Expert, not in your wildest dreams...

Dovecot error invalid service_fd

[Michel Verdier]

Hi all

I set postfix sending mails to dovecot for mailbox storage:

mailbox_transport = lmtp:unix:private/dovecot-lmtp

dovecot listen with lmtp:

service lmtp {

user = postfix
group = postfix
  }
}
passdb {

I get logs like this:

I identify 271079 as the pid for dovecot auth worker process. If I add a

service auth-worker {

}

Then I see error log coming 10 seconds after the end of every lmtp
connexion from postfix. There is no other log messages around even with
debug enable in dovecot. And mails are correctly delivered.

What am I missing ?

Re: Which takes priority, ipv4, or ipv6?

I have configured an ipv6 tunnel. If I visit this site:

However if I switch my DNS from opendns to the one provided by my ISP
and then run the "normal" test it shows the ipv6.

The note says:

(preference depends on your OS/client)

So how is the preference determined? It seems to be determined by the
DNS, but why or how do I tell for example with host -v?


That's weird… It should not be reslover-dependant unless your default 
resolver either don't support IPv6 which seems not to be the case, or 
(wrongfully) prioritize IPv4 unless the resolved name has IPv6 only?


In "normal" context, it's not determined by the DNS resolver, but it can 
be limited by the DNS resolver, of course if the resolver answers for 
IPv4 only (A record).


If the resolver can return both IPv4 and IPv6 records, and both your OS 
and application supports it, which debian does and most half-decent web 
browser do, then the OS or application config decides whether enable 
IPv6 or not.  If IPv6 is enabled, it should be prioritized and IPv4 is 
used as fallback if IPv6 fails (e.g, when connecting to an IPv4 only 
server, or using IPv4 only resolvers, if those still exist).


For debian and multiple other distros, it depends on systemd settings. 
On debian, IPv6 can be disabled in /etc/sysctl.conf, as far as I know it 
is enabled by default, unless need to add line(s) like


net.ipv6.conf.all.disable_ipv6 = 1

To /etc/sysctl.conf, then reload the file with sysctl command, or 
reboot. Note that "=1" mean disable, NOT enable, since the option names 
are in the negative form.


PS: For Non-debian-like systemd-based distros, espcially RHEL, Fedora 
and so on have a different path for these options. I don't remember the 
exact but there's no /etc/sysctl.conf
And For non-systemd distros, it is usually a bootloader option. for 
GRUB, it's the "ipv6.disable=1" parameter to the 
"GRUB_CMDLINE_LINUX_DEFAULT" in "/etc/default/grub" file

The two packages depend on different collections of supporting

And so, depending on which package you remove --- guile-2.2-libs or
w3m --- a different set of automatically-installed packages will be
left installed for no apparent purpose (because the package they were
installed to support is now gone), and eligible for autoremoval.

This mostly obvious fact (which wasn't obvious to me yesterday) is
obscured by the sheer number of packages *already* eligible for
autoremoval on the system, before removing either of the two packages
in question.

The large number is probably primarily packages that roundcube depends 
upon - but roundcube disappeared during the upgrade.  When I've seen the 
system being stable for a while, I'll reinstall roundcube - and it that 
goes well, do an autoremove.

The wiki actually says "Upgrading from one stable release to the next
(e.g. buster to bullseye) is done by following the release notes for
your architecture." You did the right thing if you followed those.

For sure, many ways work for upgrading Debian. The best tested way is
the one in the release notes.

In my experience it's been enough to install linux-image-amd64 and
linux-headers-amd64. When I run apt upgrade both are updated if new
versions are available.

Yes, the compose key is the preferred method, but for symbols that are not
available for it, the above method remains.

Example: 
'black heart' ♥  = compose key + <3
'white heart' ♡  = the above method with U2661

gucharmap may be used to find the codes, and I also found
https://unicode-explorer.com to be very useful.

And if you use a symbol like ♡ more often, you can turn it into a
character to be used with the compose key yourself, like David Wright
described.

So, to rule out possible software issues, I've done a clean install of
Bookworm and Bullseye, and this issue still happens.  I guess this
largely lowers the possibility of a software cause.  I've also done a
10-hour memtest session and it passed so I guess it was proven to be
clean as well.

For the next step, I'll go with the hardware aspect.  I want to thank
for the helps, suggestions, and brainstorming from various people from
#debian{,-next} IRC channels!  Will try to get to the bottom of this.

I use exclusively apt-hyphenated commands (apt-{get,cache,etc}), and

I have

 $ cat /etc/apt/apt.conf.d/90no_color
 APT::Color "false";

So I am surprised to learn that the newfangled bare "apt" ignores that
preference. Not a pleasant surprise.

Like I said though, I don't plan to start using it.


It appears that it is, just badly documented.

In /etc/apt/apt.conf, you can specify the escape sequences for
colors like this:

APT::Color::Yellow "ESC[33m";


This seems less general a solution than warranted. If the user can't
see yellow, they don't only want *apt* to use an alternate color for
yellow.

I would instead want to tweak the whole console color scheme along
these lines,

  https://nethackwiki.com/wiki/Colors#Linux_console

so that the colors were more sensible across all applications.


unicorn:~$ man apt.conf | grep -i -e color -e colour
unicorn:~$ man apt-config | grep -i -e color -e colour
unicorn:~$

Yeah, that's "badly documented" i.e. "not documented at all".

Here are some other things one might find by poking around the web or
various commands:

apt-config(8)
   dump
   Just show the contents of the configuration space.

unicorn:~$ apt-config dump | grep -i -e color -e colour
Binary::apt::APT::Color "1";

So, there's a quasi-visible configuration element that lets you turn off
apt's use of colors completely.  Undocumented, obviously.


Doesn't work for me.

 # apt -o "Binary::apt::APT::Color=0" update

"N% [Working]" etc output is still colorised.


Your APT::Color::Yellow is not even visible in the dump of all the
configuration elements.


contains:

   apt::moo::color "";

   apt::color::highlight "";
   apt::color::neutral "";

   APT::Color "";

I have no idea how out of date or inaccurate these may be.

It's also incredibly difficult to TEST any changes to apt's color
configuration, because the parts I care about are circumstantial.
The yellow color is used on the progress/status line while apt
is downloading stuff -- and if you've already run "apt update" earlier
today, chances are there won't be any new data to download when you run
it a second time.

If I use "apt search google-chrome-stable" I get the following text:

unicorn:~$ apt search google-chrome-stable
Sorting... Done
Full Text Search... Done
google-chrome-stable/stable,now 111.0.5563.110-1 amd64 [installed]
 The web browser from Google

where the package name (google-chrome-stable) appears green.  So...
can I test using that?  It appears I cannot.

If I put Binary::apt::APT::Color "0"; in my /etc/apt/apt.conf.d/99local
file, and re-run the apt search command, it's still green.

[rest trimmed]

Would you like blinking text instead? (Or whatever your terminal does
instead of blinking text.)

 # apt -o "APT::Color::Highlight=^[[5m" search nethack
 ^^
 (raw escape)
   (entered with Ctrl-V followed by hitting Esc key)
 (explained for benefit of readers as clueless as myself)

I got the blinking text thing from console_codes(4), under section
"ECMA-48 Set Graphics Rendition".

According to that same section, replacing "5" with "25" sets "blink
off"

 # apt -o "APT::Color::Highlight=^[[25m" search nethack

For me, this produces text in the default style (no highlights, no
colors).
