Comment 6 for bug 1596474

Proposed fixes the issue for me too:

Old:
root@homebox:~# dpkg -s openipmi | grep Version
Version: 2.0.18-0ubuntu11
root@homebox:~# /bin/systemctl enable openipmi
openipmi.service is not a native service, redirecting to systemd-sysv-install
Executing /lib/systemd/systemd-sysv-install enable openipmi
update-rc.d: error: openipmi Default-Start contains no runlevels, aborting.

Proposed
root@homebox:~# apt-get install openipmi/xenial-proposed
[...]
root@homebox:~# dpkg -s openipmi | grep Version
Version: 2.0.18-0ubuntu11.1
root@homebox:~# /bin/systemctl enable openipmi
openipmi.service is not a native service, redirecting to systemd-sysv-install
