Fix Error fwupd-refresh

Introduction

After installing monitoring (check_mk) I realized that the servis fwupd-refresh produces a critical error. However, this is based on a configuration mishap in the service itself. Here is the fix.

The service is able to perform a firmware update on UEFI machines. The service is totally useless on VMs.

Correction Step-by-Step

Edit file /lib/systemd/system/fwupd-refresh.service

Replace SuccessExitStatus=2 with SuccessExitStatus=1

Restart the service: 

systemctl daemon-reload && sudo systemctl start fwupd-refresh.service

Check the service

systemctl status fwupd-refresh.service

Disable the service

Another possibility is to disable the service:

systemctl disable fwupd
