[Bug 1642966] Re: package cups-daemon 2.1.3-4 failed to install/upgrade: subprocess new pre-removal script returned error exit status 1

> In CUPS everything is OK and as intended.

No -- as above, the maintainer scripts need to stop cups.{socket,path}
first before stopping cups.service. Also, as it seems you can entirely
drop that .path unit as it's fairly useless -- we don't start cups on
demand, but it always starts on boot (in a default install). It would of
course be nice to fix that (as I suggested in the upstream bug).

> And there is also another bug in systemd: The *.path file as it comes
with CUPS should always start CUPS (if it is not already running) if
there is the keepalive file, not only if the keepalive file is newly
created.

It does -- that's precisely what happens here: The path unit restarts
cups after the maintainer scripts stop it, and that's the core of this
bug. So if anything, you want it to be less aggressive, not more :-)

> cups-browsed.service contains "After=cups.service avahi-
daemon.service" in its [Unit] section. Is this enough to make cups-
browsed being shut down before the shutdown of CUPS is done?

Yes, it is, the Before/After get inversed on stopping units.
