[Bug 1314739] Re: Unable to upgrade from 13.10 to 14.04

[Brian Murray]

The upgrade fails because of at least this package:

xserver-xorg-video-intel 2:2.99.911+git1404231930.5fbbfd~gd~s 0

This is from a PPA and not the official Ubuntu repositories and includes
a version number greater than the package provided by the official
Ubuntu repositories.  Subsequently, the upgrade is unable to succeed.
You'll need to use the tool ppa-purge to install the official version of
the Ubuntu packages and disable the PPA before the upgrade can succeed.
Thanks and good luck.

Title:
  Unable to upgrade from 13.10 to 14.04

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

Bug description:
  When I execute:
  sudo do-release-upgrade

  in the terminal, it gets to the point where it says:
    Calculating the changes
    Calculating the changes

  and then 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 

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

  As none of the above applies, I'm mystified as to why this is
  happening.
