[Bug 1574566] Re: package libvirt-bin 1.3.1-1ubuntu10 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Yes, I did. If you don't, you get a warning.

However, after thorough research, I noticed some leftovers from a previously installed libvirt 1.3.3 from sources over 1.3.1.
Uninstalling the latter did not uninstall everything, hence the mess.
After cleaning everything and reinstalling libvirt 1.3.1 without 1.3.3, I was even able to correctly start libvirt-bin without having to modify the service file.
I then modified it with NotifyAccess=all, systemctl daemon-reload & systemctl restart libvirt-bin: everything works fine so far:
systemctl status libvirt-bin
