Version7 is what you mean. I use 6.9 on both client and server.

Adding these ciphers doesn't help - same algo error,
Thats wired coz I can ssh to the server without any issues.

Hi
I'm connecting from a Mac (X2Go Client v. 4.0.5.1 (Qt - 4.8.7)) to
Fedora 24 with a xfce session using the
x2goserver-4.0.1.19-11.fc24.x86_64 packages from the fedora repos.
On starting emacs, I get the error below. This issue seems to have been
around for a while in similar forms, but didn't affect me under Fedora 22.
Is anyone in a position to confirm this issue on Fedora 24 and suggest a
work around? I tried setting various environment variables suggested on
various web pages for …
[View More]similar issues and in the bug report noted in the
error message (and checked /etc/PROBLEMS), but nothing was effective.
emacs starts fine in an xfce session at the console.
Thanks

Hi All,
This perhaps is a trivial question: but is it possible to somehow
log/check history of past x2go session on the server?

I am not able to get the basic Shared Folder capability to run.
Debian 7 Linux OS on client and server, X2go V 4.0.3.0, and XFCE Desktop.
Is there something fundamental preventing this from working?
Thanks in advance,

Hi all.
First of all, I'd like to congratulate all the
contributors for this great work.
X2go is a professional class tool
for remote desktop.
However... I ran into a really special thing using
the windows agent in its last version (4.0.5).
Sometimes, when you
open the session, the "Num Lock" is usable, sometimes not. I mean,
sometimes you may push the caps lock button and switch from arrows to
Numeric keys, and sometimes the Key Pad is fully unusable. It happens
only on windows agent …
[View More]as far as I know.
All that I tried did not solve
the issue. Did you already encounter that?
Thanks.

Hello,
I have upgraded to 4.0.4.0 on win32.
It's a minor thing but if I now set a session icon for a connection it
is not displayed and I get blank instead.
Is there something I need to do to get this to work?
Thanks

Hi
In order to lower resource stress when building packages, I plan to deprecate
support for distributions that have reached End Of Life on September 4th 2016.
This includes the following distro versions:
- Debian:
o 6.0 "squeeze"
- Fedora
o 19
o 20
o 21
o 22
- OpenSuSE
o 12.2
o 12.3
o 13.1
- SuSE Linux Enterprise Desktop (not Server!)
o 11.2
o 11.3
After deprecation, no new builds will be published and existing builds will be
deleted from the repositories to …
[View More]discourage users from installing unmaintained
software.

Hello everybody,
I'm new in your community and I'm pleased to be with you, thanks very much you for your work!!!!!!!!!!!
X2GO is a very good product because the applications are numerous and reliables ...
To begin simply, I have just one question; Does it exists an X2GO Server for SOLARIS SPARC ?
I really hope that someone would able to respond me, please !
Best regards.

Hi,
Just a quick update on this (I've not resolved it unfortunately)....
I thought I'd try the git version RPMs rather than the EPEL el7 versions,
so I'm now running:
