After a lot of digging, it seems that I have an unexpected, but simple work-around for getting firefox to work under x2go on ubuntu 22.04:
Add to ~/.bashrc: unset DBUS_SESSION_BUS_ADDRESS I tried putting this unset command in xinitrc right before xfce4-session is run. No luck. I tried the unset in a custom script that calls xfce4-session from x2go: no luck. I tried the unset in 95bdbu_update-activation-env: no luck. It seems that xfce4-session is restoring the environment variable. This is unexpected, and may represent a bug in xfce4-session, or possibly in ubuntu's latest changes. I looked in the source for xfce4-session, but it wasn't readily obvious that it was doing anything that would cause this to be set. I'd love to produce a proper fix if someone can give me a clue where to look, but at least I/we have a quick work-around. Can anyone else confirm that this fix works for them? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1951491 Title: Can't run snaps: .slice/session-1.scope is not a snap cgroup Status in X2Go: New Status in snapd package in Ubuntu: Invalid Status in systemd package in Ubuntu: Incomplete Status in x2goserver package in Ubuntu: Confirmed Status in snapd package in Debian: New Bug description: I just upgraded from hirsute to impish using do-release-upgrade. On the upgraded system, I can't run either firefox or chromium (both of which worked fine under hirsute). Both fail with: /user.slice/user-NNN.slice/session-1.scope is not a snap cgroup where NNN is my uid With firefox, I was able to fix the problem with: snap remove --purge firefox apt purge firefox apt install firefox Now firefox works. But I tried the same thing substituting chromium- browser for firefox, and it didn't help: chromium fails with the same error message. I guess there must be something left over from the hirsute version of snapd that isn't getting noticed or cleared by the impish version? Someone suggested this might be related to bug 1850667, but that bug is marked fixed as of a couple months ago, and I just did this upgrade today. Also, it doesn't mention the error message I'm seeing.
