unconfinded snaps don't have thie problem (that is, --classic snaps), these bypass all the snap sandboxing and I guess this means they bypass the controls and restrictions of cgroups. If you want this fixed, you have to get x2go fixed. Report the bug there.

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.
