Bug#943343: fwupd: fwupd-refresh.service failed to start Refresh fwupd metadata and update motd.

[Thomas Stewart <thomas@stewarts.org.uk>]

Hi,

I'm running testing/sid and have fwupd-1.5.5-2 installed. I have found
that when fwupd-refresh.service restarts either with the timer or
manually that if DynamicUser=yes is enabled then the service fails to
start[0]. When I remove DynamicUser from the unit it restarts fine.

I noticed that the unit has: CacheDirectory=fwupdmgr but the
metadata seems to live in /var/cache/fwupd[1].

After purging the package and removing /var/cache/fwup* /var/lib/fwupd
/var/cache/private/fwupd and reinstalling I can see the /var/cache dirs
created[2] but the service does not start.

When removing the "StandardError=null" directive from the unit I get an
additional error[3], which seems to indicate it's having trouble
talking to dbus.

Kind Regards
