Bug Description

First time using the upgrade tools to move to next LTS release of Kubuntu. Encountered error message "Could not calculate the upgrade". Once this message occurs, upgrade process ends. Not completely sure this is a bug, but message treed is pretty non-specific. I have only stayed with LTS distribution. Have never actually tried pre-release or short term release versions.

I have verified I do not have any non-supported software in place currently on system that is running 12.04 LTS release. I have reviewed the current configuration of software sources in MUOn manager to make sure there isn't something unusual there. I cocnsistently run into the error above during the cycle of Setting new software channels.

After posting the log files here, I started reviewing the log files for errors. Found errors re: package Flightgear simulator in the log. I removed this package from my system and attempted install again. I have now moved past this original error and am in the middle of upgrade. Will post another comment in this report on the results after this error.
