I hit that again today on an upgrade.
Network manager didn't come up again.

But that still isn't the root cause.


And before this plenty of things failed on GetNameOwner() in that sense
it is similar to the former occurance.

I also have a bunch of crash files again, but all of them are apps going down due to the gnome shell reset

And again dbus seems to have timed out:

Bug description:
  This morning I found my computer on the login screen.
  But not the one of the screen log, no a new one - so something must have crashed.

  Logging in again confirmed that all apps were gone and the gnome shell
  was brought down what seems like triggered by a background update o
  accountsservice.

  As always things are not perfectly clear :-/
  The following goes *back* in time through my logs one by one.

  Multiple apps crashed at 06:09, but we will find later that this is a follow on issue of the underlying gnome/X/... recycling.

  rdkit was failing fast and giving up (that will be a different bug, it just seems broken on my system):
  Apr 08 06:10:13 Keschdeichel systemd[1]: Started RealtimeKit Scheduling Policy Service.

  But that already was only triggered by a gnome restart that kicked of earlier:

  Apr 08 06:09:27 Keschdeichel systemd[1726656]: Started GNOME Shell on Wayland.
  Apr 08 06:09:27 Keschdeichel systemd[1726656]: Reached target GNOME Shell on Wayland.

  X was recycleing before:

  Apr 08 06:09:22 Keschdeichel /usr/lib/gdm3/gdm-x-session[10710]: (II) Server terminated successfully (0). Closing log file.

  
  It seems like some internal service broke and everything that followed was a secondary issue to that:

  The last things before was systemd reload - maybe due to a background
  upgrade?
