Dear Maintainer,
I upgraded to gdm 49.1 from Experimental, and now GDM3 fails to start: it just
hangs.
In the logs I found this error:
unix_chkpwd[2062]: could not obtain user info (gdm-greeter)
I found this similar bug:
https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/2121017
I do have libnss-systemd 258.1-1 installed and /etc/nsswitch.conf contains
passwd: files systemd
group: files systemd
There was also an AppArmor profile preventing access to the new gdm
userdb service.
See bug https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2119541
and the fix https://gitlab.com/apparmor/apparmor/-/merge_requests/1761
which you can apply to your local
/etc/apparmor.d/abstractions/nss-systemd file
