[Bug 1241391] Re: Release upgrade to 13.10 breaks on Macbook Pro Retina 15"

[Brian Murray]

The PPA page contains the following text:

"To revert to official packages, install the ppa-purge package and run
"sudo ppa-purge xorg-edgers". Note: This currently has issues in oneiric
because ppa-purge there does not work with multiarch. ppa-purge packages
from this PPA do purge correctly on precise and newer."

  Could not calculate the upgrade

  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.

  I'm not aware of running pre-release software or any unofficial
  software packages (what is that anyway? It should not effect the
  installation process)
