[Bug 1931722] Re: software-properties-gtk generates python errors

[W. Bourgeois]

I'm attaching the contents of sudo systemctl status as a text file.

It appears that I can actually launch software-properties,  but only as
sudo. The direct link in the Ubuntu menu won't work.

It seems it is more related to dbus, but I am not sure.
