Right, having multiple metapackages like ubuntu-desktop and mythbuntu-
desktop can create issues for the package problem resolver.

Title:
  Could not calclate the upgrade

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

Bug description:
  I've got a bone stock Ubuntu install that I've converted over to a
  MythTV frontend running 14.04 on an Atom box.  Upgrading to 16.04
  seems to fail and give a could not calculate the upgrade message.
  Nothing is pre-release on here.  It asked if nothing was pre-rel to
  submit a bug so I'm doing so.  Hopefully it helps.  Going to keep
  trying for a bit but if I can't get it I may just wipe and install
  16.04 clean.  Hope not to have to though.
