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 -- Tom [0] $ sudo systemctl restart fwupd-refresh.service Job for fwupd-refresh.service failed because the control process exited with error code.
