Package: pyhoca-cli Version: 0.5.0.2 Severity: minor Client OS: Fedora 22 64-bit (with latest updates. In beta, but about to be released.) pyhoca-cli 0.5.0.2-1.fc22 (Fedora's package) python-x2go 0.5.0.3-1.fc22 (Fedora's package) Server OS: Fedora 21 64-bit (with latest updates) running in a Docker container DockerFile: https://github.com/mikedep333/Fedora-Dockerfiles/blob/add-x2go/x2go/x2go-minimal/Dockerfile x2goserver 4.0.1.19-1.fc21 (Fedora's package) x2goserver-xsession 4.0.1.19-1.fc21 (Fedora's package) nxagent 3.5.0.29-1.fc21 (Fedora's package) x2goagent 3.5.0.29-1.fc21 (Fedora's package) Note: Even if you are unfamiliar with Docker, you should be able to make sense of the Dockerfile. Note that it is based on the "fedora" image, which is a very minimal install of Fedora. Also note that "start.sh" simply adds a user account named "user" with a fixed password. When I connect to a new TERMINAL session (which defaults to lxterminal), the session appears to work fine. However, at the end, I often receive an exception like: x2go.x2go_exceptions.X2GoSessionRegistryException: No session found for UUID a2f17c6e-fe14-11e4-8e21-001a4a1bd601 I am using this command to connect: pyhoca-cli --server 127.0.0.1 -p 50000 -N --user user --add-to-known-hosts --libdebug --debug See attachment for output. This bug is reproducible, but not 100% of the time. It seems to be related to timing. It is usually reproduced when I leave lxterminal open for 10 seconds. (I close lxterminal by typing "exit" or clicking the X in the window decoration.) It is usually NOT reproduced when I leave lxterminal open for 2 seconds.
