[Bug 1241091] Re: Can't upgrade from 13.04 to 13.10

[Brian Murray]

The upgrader failed to calculate the upgrade due to a PPA from which you
have installed some different video drivers.  You'll need to revert to
the official versions of Xorg packages using ppa-purge for the upgrade
to proceed.  Thanks and good luck!

** Changed in: ubuntu-release-upgrader (Ubuntu)
       Status: Confirmed => Invalid

** Tags added: ppa

Title:
  Can't upgrade from 13.04 to 13.10

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

Bug description:
  Can't upgrade. Upgrade app says:

  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 

  I had a release version.

  $ lsb_release -rd
  Description:	Ubuntu 13.04
  Release:	13.04

  Steps to reproduce:
  1) Open update app, click update
  2) Accept release notes
  3) Get error.
