The output in comment #8 shows that this system is running upstart despite being 16.04. Upstart is not supported as init on 16.04 except during the upgrade. This bug appears to have been fixed for the systemd unit, but not for the upstart job. A simple reboot to systemd should suffice to fix the problem on 16.04.
