Failing to install NUT

Carlos Hartmann · December 11, 2021

Hi!

I'm trying to install NUT because I connected a UPS device. I'd like to get it working so that the server is shutdown safely when there is a power interruption and that I get an e-mail notifying me as soon as there is an interruption.

Already after installing via

sudo apt install nut nut-client nut-server

I get the following warnings:

Setting up nut-client (2.7.4-8) ...
Job for nut-monitor.service failed because the service did not take the steps required by its unit configuration.
See "systemctl status nut-monitor.service" and "journalctl -xe" for details.
invoke-rc.d: initscript nut-client, action "restart" failed.

And the output of systemctl status nut-monitor.service is:

And I can't use stuf like nut-scanner so the packages aren't completely installed. Googling around just confused me because it's not even clear to me where the mistake is or how to fix it.

Any help is appreciated, even if just in form of "go there and ask them".
