Thank you Christian, I remember this from many months ago, (I think), unless this is a new bug. I only had one problem
once lately but I am not worried about it. Thanks for doing anything but don't waste your time on Me! (unless it affects other people)
Take care and you are appreciated!
Sincerely

 I didn't find anything more on this case, neither a great idea on the
bit we have nor anyone else being affected. In the try to focus on what
is important I'd close the bug to have a better view on what is left to
tackle.

Bug description:
  upgraded from 16.04? to 18.04 at end of upgrade I got libvirt-daemon-system error 128.
  I didn't change anything in the /etc/livirt/nwfilter... files like the system
  now accuses me of doing! I logged in this time through Unity to get my old desktop back and that is when I got this system report.
  I was getting a system error when I logged in after the upgrade but no error # or anything;
