package systemd 229-4ubuntu13 failed to install/upgrade: subprocess installed pre-removal script returned error exit status 2

[Peter Freeth]

The error message appears after the desktop loads on Ubuntu 16.04 which I recently upgraded from 15.10.

The system asks me if I want to report the problem, other than that, I know nothing.
