You have been subscribed to a public bug: A fresh install of 12.04.3 fails to upgrade to 14.04.
To reproduce: 1) Install 12.04.3 (I am using the amd64 version in a virtualbox VM) 2) Install all available software updates 3) Run update-manager -d to force the upgrade to the development release of Ubuntu Expected results: The upgrade runs and completes Actual results: update-manager reports "Could not calculate the upgrade. An unresolvable probolem occured while calculating the uprade". There are no details in the error dialog about what went wrong. >From /var/log/dist-upgrade/main.log it looks like a packaging problem results in unity being selected for removal, which is not valid because unity is in the blacklist of packages that should not be removed on upgrade.
