fwupd-refresh.service fails to start on focal

[imker]

Hello,

since the 18 of April 2020 some of my Ubuntu 20.04 (focal) installations report the following error:

May 18 17:27:06 city systemd[1]: Starting Refresh fwupd metadata and update motd...
May 18 17:27:06 city systemd[1]: fwupd-refresh.service: Main process exited, code=exited, status=1/FAILURE
May 18 17:27:06 city systemd[1]: fwupd-refresh.service: Failed with result 'exit-code'.
May 18 17:27:06 city systemd[1]: Failed to start Refresh fwupd metadata and update motd.

At first I thought this is sporadic and will go away, but since one month this error is reported constantly.

This only happens on machines that was installed from a focal ISO file. Installations that was upgraded form earlier Ubuntu version to focal work fine. Also machines that are already on a newer Version of Ubuntu don't show this problem.

Trying to start the fwupd-refresh.service manually on the affected machines shows the following:

sudo systemctl status fwupd-refresh
