Comment 23 for bug 1960336

from the newly installed system with 20.04, warnings came for /var/lib/gdm3.config and .local not being empty.
root@ubuntu-inspiron-5482:/var/lib/gdm3# ls -lrta
total 32
drwxr-xr-x 3 root root 4096 feb 5 12:33 .config

drwx------ 4 gdm gdm 4096 feb 5 12:35 .local

is what that looks like on the broken system.

On the one with warning, it shows 755 instead of 700 permissions.
There is also no .nv dir.
I will wipe it out, reinstall and see what happens.
