Powernap 2.21 fails to start on Ubuntu 16.04.1

[David Partridge]

When trying to start powernap I get

Failed to start powernap.service: Unit network.service failed to load:

Change /lib/systemd/system/powernap.service

From:
 Requires=network.service
 After=network.service

To:
 Requires=networking.service
 After=networking.service

Add line at end of [Services] section:

 RemainAfterExit=yes

After changes whole file looks like:

amonra@Charon:~$ cat /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

Don't forget to do:
systemctl daemon-reload

for the changes to take effect before
systemctl start powernap

I'm using Ubuntu 18.04 and I've also affected this bug.
I followed description above, and it resolved my issue.
