Dear all, I've been using X2Go on a pair of openSUSE Tumbleweed systems. On 2022-05-23 I did a dist-upgrade on both and now I'm no longer able to run a remote application or desktop via X2Go -- the client successfully connects to the server but then immediately disconnects. There's nothing obvious in the client and server logs (even at debug-level verbosity) that explains the immediate disconnects -- I see the client successfully connecting to the server and then immediately disconnecting. (Still, I can provide the logs on request.) Some additional relevant pieces of information: * The problem occurs regardless which remote application or desktop I'm trying to run. I've tried xfce4-terminal, xterm, icewm, and others. * The client has no problem connecting to the Tumbleweed server directly via ssh -X and running remote applications. * The client has no problem connecting to an X2Go server running on a different machine running Leap 15.3. * X2Go itself was not updated in the dist-upgrade. * I've tried upgrading to the latest development versions of x2goserver and x2goclient but this hasn't helped. ( I am thinking that some security-hardening update may be at fault here. I tried temporarily disabling AppArmor on the server but that didn't work around the problem. And it doesn't look like the server's sshd_config file was touched in the dist-upgrade. Can anyone suggest any further troubleshooting steps? If anyone cares to do any testing themselves, my packages for the latest x2goserver, x2goclient, nx-libs, and pinentry-x2go are available at <https://download.opensuse.org/repositories/home:/psych0naut:/x2go/openSUSE_Tumbleweed/>.
