Comment 6 for bug 1760391

Hello,

I got the same error with Ubuntu 18.04.5 LTS.

Last comment was not enough for me.
I needed to start acpid.socket before.

My solution :

root@M076-1603001:~# dpkg --configure -a
Paramétrage de acpid (1:2.0.28-1ubuntu1) ...
Job for acpid.service failed because of unavailable resources or another system error.
See "systemctl status acpid.service" and "journalctl -xe" for details.
