[Bug 1079354] Re: Error upgrading from 12.04 to 12.10

[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.

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

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

** Tags added: ppa xorg-edgers-ppa

  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.
