[Bug 1766962] Re: git clone fails with "An unexpected TLS packet was received" error

2018-04-25 Thread thomas duriez
Sorry, this is solved, I just had to set

git config --global https.proxy

why this was not retained when upgrading from 16.04 or why it needs now
to be set (the $https_proxy environment variable is correctly set) is
still a problem though.

[Bug 1766962] [NEW] git clone fails with "An unexpected TLS packet was received" error

2018-04-25 Thread thomas duriez
Public bug reported:

I just updated from 16.04 to 18.04 beta.

This is the error message I get when I try to clone a repo:

fatal: unable to access 'https://github.com/xxx/y.git/':
gnutls_handshake() failed: An unexpected TLS packet was received.


I cannot clone repositories on internet (tried on github and overleaf) when I 
used to have no pb.
This applies to https repositories (Couldn't try over ssh, IT decision).
I built this version of git to use libcurl4-openssl instead of libcurl4-gnutls 
to no avail but with a different error message though:

fatal: unable to access 'https://github.com/xxx/y.git/':
error:1408F10B:SSL routines:ssl3_get_record:wrong version number

I purged packages and deleted .gitconfig, without results.

[Bug 1726595] Re: Running Matlab (R) from ssh session with X forwarding doesn't work anymore in 17.10

2017-10-25 Thread thomas duriez
As a matter of fact, I just checked the bug happens with scilab,
available in universe. Scilab returns some interesting debug info in the
standard output, which O copy in the attached text file.

NEW INFO.

I didn't see before that matlab was generating a crash log for this. This log 
confirms that the error comes from java:
"Assertion in void {anonymous}::mwJavaAbort() at javainit.cpp line 1411:
Fatal Java Exception.  See Java Crash Report for details."

The java crash report gives the following:

 Operating System: Linux 4.10.0-37-generic #41-Ubuntu SMP Fri Oct 6 20:20:37 
UTC 2017 x86_64
  Processor ID: x86 Family 6 Model 60 Stepping 3, GenuineIntel
  Host Name:
FATAL ERROR in native method: Nativewindow X11 IOError: Display 0x7fb2cb9e5210

at sun.awt.X11.XToolkit.run(Unknown Source)
at sun.awt.X11.XToolkit.run(Unknown Source)

Which says that X11 is at fault.

2017-10-25 Thread thomas duriez
I will try. For the moment I double boot 16.04 because I need to have it
working, but I can run tests on spare time. Because I couldn't find
problems when not running the java machine of Matlab  I will focus on
applications relying heavily on java. If you have any suggestion it
would help. Thanks again for your time.

2017-10-25 Thread thomas duriez
1- Yes Matlab works as expected without going through ssh.

2- Repeat the above but first do a "ssh -X localhost" triggers the
problem.

3- Both scenarios hold regardless of how I login ("Ubuntu", "Ubuntu on
Xorg" or "Unity").

As you mentionned the DISPLAY variable I checked the following (maybe it was 
obvious, but not to me):
 - ssh@localhost
 - echo $DISPLAY returns localhost:10.0
 - export DISPLAY=:0
 - matlab & then plot(1,1). 
 - it works. (tested in "Ubuntu", "Ubuntu on Xorg" and "Unity")

[Bug 1726595] Re: Running Matlab (R) from ssh session with X forwarding doesn't work anymore in 17.10

2017-10-24 Thread thomas duriez
Dear Andreas,

It was tried in all three modes. 
Furthermore how do I enforce Xorg when I log from another machine (in my case a 
windows running Xming) to this one ?
I suspect once I connect through ssh with X11 forwarding, the session is Xorg.  

Thanks for your time.

[Bug 1726595] [NEW] Running Matlab (R) from ssh session with X forwarding doesn't work anymore in 17.10

2017-10-23 Thread thomas duriez
Public bug reported:

OBSERVED BEHAVIOR:
Matlab stays in busy state when using some functions like "plot" or even 
"exit", while executing through a ssh tunnel with X11 forwarding. 

REPRODUCE THE BUG:

You need matlab (my version is R2017a) to reproduce the bug. I suspect
any version >= 2014b would reproduce the bug (HG2 framework), and maybe
any version.

1. Connect to self (or from other machine) with X forwarding:
$ ssh -X user@localhost

2. Launch matlab
$ matlab &

3. Plot something
>> plot(1,1)

ADDITIONAL INFORMATION
- Normal behavior would be appearance of a new window and a single point at 
position (1,1). 
- No ressources seem to be used. 
- Opening a figure alone is possible. (>> figure). Opening other windows from 
the graphical user interface is possible 
- Opening Matlab without the java machine seems to work, but matlab relies 
heavily on java. At least "exit" which doesn't work with java, works without 
java.
- Providing Matlab with open-jdk version 1.8.0_144 didn't change anything.
- This used to work perfectly for as long as I have been using Ubuntu (since 
2012).

[Bug 1637002] Re: gedit crashes with segmentation fault at launch

2016-10-26 Thread thomas duriez
I actually managed to get it working by calling:

gksudo gedit

After that, I can't reproduce the bug anymore. 
Calling gedit (without gksudo and through any launcher or in terminal) works 
perfectly now.

[Bug 1637002] [NEW] gedit crashes with segmentation fault at launch

2016-10-26 Thread thomas duriez
Public bug reported:

I am running Ubuntu 16.10, with gedit 3.22.0 on it. Whenever I try to
have gedit running, I obtain the following output:

ViolaciĆ³n de segmento (`core' generado)

Which is spanish for "Segmentation fault (core dumped)" I guess.

dmesg returns:
[ 1596.185619] gedit[11005]: segfault at 0 ip 7f227efa5f80 sp 
7ffce4a78bc8 error 4 in libgio-2.0.so.0.5000.0[7f227eefe000+18d000]

So I reinstalled libgio-2.0-0 (2.50.0-1), without results.

This is as far as I can go.
