If this bug report is about a failure to calculate the upgrade then it is because you have enabled a PPA which provides xorg packages that have greater version numbers than the release to which you are trying to upgrade. Please install the package ppa-purge and use the tool it provides, called ppa-purge, to remove the PPA and restore the official version of the package and try the upgrade again. If that is not the issue you are trying to report please reopen the bug.
