I recently had reported installing x2goserver on a totally new server machine and the x2goclient on a totally new client machine both running Ubuntu 12.04 beta 2 and the fact that when trying to start an x2go session it would always indicate "running" then immediately fail/terminate.<br>
<br>I've found out the following.<br><br>After adding the x2go PPA for debian/ubuntu<br><br><b>sudo add-apt-repository ppa:x2go/stable<br>sudo apt-get update</b><br><br>In the past all I've had to do on the server was install x2goserver<br>
<br><b>sudo apt-get install x2goserver</b><br><br>then edit /etc/ssh/sshd_config and enable ChallengeResponseAuthentication to YES<br><br><b>ChallengeResponseAuthentication yes</b><br><br>However, with the new x2go versions apparently that is NOT they only module that needs to be installed.<br>
<br>On the server you now also must install x2goserver-xsession<br><b><br>sudo apt-get install x2goserver-xsession</b><br><br>My best guess is that this was introduced when the new x2go versions implemented the ability to <b>published apps</b> on the x2go server without having to install any sort of desktop environment on the remote "server" machine.<br>
<br>After installing the x2goserver-xsession the x2goclient now successfully creates a remote desktop session with one caveate... I've had to setup the remote server for ssh automatic login <br><br>If using Ubuntu refer to: <a href="https://help.ubuntu.com/community/SSH/OpenSSH/Keys">https://help.ubuntu.com/community/SSH/OpenSSH/Keys</a><br>
<br>If I do not do this then the login to the remote server will always fail due to some ssh failure but I am not sure if its the client or server side that fails but that is another problem to figure out later. At least I can get a remote desktop now.<br>
<br>I'm not sure if the above change was documented anywhere on the x2go wiki but I will check and add it if it doesn't exist yet.<br><br>Brian<br><br><br><br>
