I want to shut down or suspend my little home server after a while and wake it when a magic packet comes so I've installed powernap to suspend my server. But when trying to start powernap service with sudo service powernap start it gives me an error: Failed to start powernap.service: Unit network.service not found. I use Ubuntu 18.04.3 LTS

with ethtool I don't know how to set permanently the wake-on on g

any help? :D

I experienced the same problem. This is a known bug with a workaround here: https://bugs.launchpad.net/powernap/+bug/1608057

Edit: /lib/systemd/system/powernap.service

[Unit]
Description=PowerNap
Requires=networking.service
After=networking.service

[Service]
Type=forking
ExecStartPre=/usr/share/powernap/powernap-ethtool
ExecStart=/usr/sbin/powernapd
ExecStop=-/usr/sbin/powerwake-now
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

Then restart powernap:

sudo systemctl daemon-reload
sudo systemctl start powernap
