Bug Description
When I run Software Updater to upgrade from 14.04 to 14.10, I get an error message:
"Could not determine 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-
Okay, fair enough, I've installed several packages from PPAs that could potentially cause a conflict. My problem is, this error message gives no useful information to target the problem. The "Terminal" arrow in the Distribution Upgrade window is greyed out, so I cannot see the output to find out what packages might be conflicting. I finally found the file /var/log/
This error message needs to provide the user with some useful information to solve the problem, at the very *least* pointing them to the apt.log file.

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.
