Failed to power off system via logind: Unit systemd-poweroff.service has a bad unit file setting.

systemd[1]: systemd-poweroff.service: Service lacks both ExecStart= and ExecStop= setting. Refusing.

Adding

[Service]
ExecStart=/usr/bin/sleep 0

Solves the issue, but how did I get to have this issue to begin with?

Adding

Code: Select all

[Service]
ExecStart=/usr/bin/sleep 0 

To which file did you add that? To '/lib/systemd/system/systemd-poweroff.service'?

On my machine, '/lib/systemd/system/systemd-poweroff.service' was installed by sys-apps/systemd-239-r3. Below is the contents of the file:

Interesting, my service unit file lacked the [Service] section. It was installed by systemd. Can't recall the version of the last update and I'm far from that box. But my laptop running systemd-239-r2 does have the same service file as yours. I am certain I did not change that file.

Just checked my desktop, it's systemd-240-r3. And the unit file is does not include the [Service] section

Code: Select all

$ tar -x -f /usr/portage/distfiles/systemd-240.tar.gz systemd-240/units/systemd-poweroff.service
$ $ cat systemd-240/units/systemd-poweroff.service

Haven't checked if systemd-240-patches-2.tar.gz include patches for this nor have I gone to figure out if this is a bug upstream or in the Gentoo distribution.

Here is the commit which removed the Service section. It doesn't look like a bug.
