Hi Michael,

I've managed to debug this a bit further, and it seems to actually be #860040

When /proc is mounted with hidepid>0 /proc/1/cgroup can't be read (either
because /proc/1 doesn't exist, if hidepid=2, or because /proc/1/cgroup is not
readable, if hidepid=1).

In that case, polkit-gnome-authentication-agent-1 (or lxpolkit, for that
matter) bails out early.

I'm not entirely sure why it needs to get information about init cgroups but
the behavior looks wrong to me at first sight.

In any case, the bug is indeed not in network-manager.

Regards,
