Title:
  upgrade to 16.04 could not calculate the upgrade error

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed

Bug description:
  When upgrading from 15.10 to 16.04 went ok until we got the could not
  calculate the upgrade error message.

  I read if there are unofficial software packages it could be the
  problem. How would I know what packages are unofficial and how exactly
  would I remove them?

  Long time Ubuntu user over 7 years if that helps.
