Title:
  Cannot upgrade Kubuntu 14.04.4 LTS to 16.04.1 LTS

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

Bug description:
  Running "sudo do-release-upgrade" results in:

  An unresolvable problem occurred while calculating the upgrade

  This can be caused by: 
  * Upgrading to a pre-release version of Ubuntu 
  * Running the current pre-release version of Ubuntu 
  * Unofficial software packages not provided by Ubuntu

  There is just too much "Broken" in apt.log... gnote, xchat, even
  openjdk..? Just doesn't seem right.
