Public bug reported:
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.
