Failed clr-fwupd-update.service

I accidentally noticed that clr-fwupd-update.service was in failed state while looking for some other stuff.

$ sudo systemctl status clr-fwupd-update.service 
● clr-fwupd-update.service - Auto-firmware update
	 Loaded: loaded (/usr/lib/systemd/system/clr-fwupd-update.service; static; vendor preset: disabled)
	 Active: failed (Result: exit-code) since Tue 2020-03-10 20:44:07 CET; 26s ago

I don’t think the error was because of a misconfiguration of mine. I was able to correct the error by refreshing the metadata from the servers with the command sudo fwupdmgr refresh, maybe this command was never issued before? Now it seems to be fine:

$ sudo systemctl status clr-fwupd-update.service

I just want to report it, just in case it matters. Cheers.
