[Bug 1386780] Re: Unable to upgrade 14.04 to 14.10

Reviewing the files from your upgrade attempt you seem to have enabled a
PPA that provides Xorg packages. 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 for the xorg-edgers
PPA.  Instructions for reverting to official Xorg packages should be
similar for the PPA that you have enabled.

Title:
  Unable to upgrade 14.04 to 14.10

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

Bug description:
  I've tried the upgrade from the console and from the GUI - same
  result:

  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.
