[Bug 1313425] Re: Cannot upgrade from Xubuntu 12.10 to any version with do-release-upgrade.

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.  Thanks.

  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.
