I have VPS, and after checking systemctl, I noticed that my fwupd-refresh.service failed.

terminal

Can you explain the problem, and could you help to fix it?

In some cases this error can be safely ignored. fwupd-refresh.service just executes /usr/bin/fwupdmgr refresh command and treats exit status 2 as success (see last 2 lines of fwupd-refresh.service). But fwupdmgr can also successfully exit with status 0, which will be wrongfully interpreted by systemd as an error.

  • systemctl cat fwupd-refresh:

    # /lib/systemd/system/fwupd-refresh.service
[Unit]
Description=Refresh fwupd metadata and update motd
Documentation=man:fwupdmgr(1)
After=network.target

    [Service]
Type=oneshot
CacheDirectory=fwupdmgr
StandardError=null
DynamicUser=yes
RestrictAddressFamilies=AF_NETLINK AF_UNIX AF_INET AF_INET6
SystemCallFilter=~@mount
ProtectKernelModules=yes
ProtectControlGroups=yes
RestrictRealtime=yes
SuccessExitStatus=2
ExecStart=/usr/bin/fwupdmgr refresh

  • sudo /usr/bin/fwupdmgr refresh:

    ...
Successfully downloaded new metadata: 0 local devices supported

  • echo $?: 0

  • man fwupdmgr:

    EXIT STATUS
      Commands that successfully execute will return "0", but commands that have no actions but successfully execute will return "2".

In my own case (Ubuntu Server 20.04 with latest updates), DynamicUser=no provides quick&dirty solution.

First, run "systemctl edit fwupd-refresh" and enter:

[Service]
DynamicUser=no

Then, run "systemctl restart fwupd-refresh" and enjoy.

fwupd-refresh.service Loaded: masked

A service that is masked is disabled and can't be activated by an other unit (timers, targets, services...) that needs it or manually. It's the stronger version of disabling a service.

fwupd-refresh.timer: ...failed...unit fwupd-refresh is masked.

To change this:

sudo systemctl unmask fwupd-refresh

Then this:

sudo systemctl daemon-reload && sudo systemctl start fwupd-refresh.service
systemctl list-units --failed

If fwupd-refresh is listed as failed then:

Uncomment #DynamicUser=yes in /lib/systemd/system/fwupd-refresh.service

I've solved my problem with it https://github.com/fwupd/fwupd/wiki/PluginFlag:legacy-bios

Simply adding "bios" at the end of this line DisabledPlugins=test;invalid;bios in

/etc/fwupd/daemon.conf
