Title:
  Cannot upgrade from 12.02 to 14.01

Status in update-manager package in Ubuntu:
  New

Bug description:
  GUI tells me "new release is available" .. I click "Upgrade.". .. it
  runs a bit and then stops with an error:

  could not calculate the upgrade .. an unresolvable problem occurred while calculating the upgrade ..
  it lists 3 causes... and then instructs me to run ubuntu-bug ubuntu-release-upgrader-core in a terminal. .. which I did.

  Must I completely wipe my hard disk and do fresh install?   How can I
  find out what is causing the upgrade to fail?
