[Bug 1179102] Re: Ubuntu could not calculate upgrade

[Brian Murray]

Reviewing the files from your upgrade attempt you seem to have enabled
the xorg-edgers-ppa.  This will prevent the upgrade as that PPA contains
different versions of packages essential to Ubuntu.  The page,
https://launchpad.net/~xorg-edgers/+archive/ppa, contains details on to
how to revert to the official Xorg packages.

** Changed in: update-manager (Ubuntu)
       Status: New => Invalid

** Tags added: ppa xorg-edgers-ppa

** Package changed: update-manager (Ubuntu) => ubuntu-release-upgrader
(Ubuntu)

Title:
  Ubuntu could not calculate upgrade

Status in “ubuntu-release-upgrader” package in Ubuntu:
  Invalid

Bug description:
  This is the message that pops up:

  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade:
  E:Unable to correct problems, you have held broken packages.

   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

  If none of this applies, then please report this bug using the command
  'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.
