Public bug reported:

When I try upgrade Ubuntu 12.10 to 13.04 
I get a message "Third party sources disabled..."
sudo add-apt-repository ppa:tualatrix/ppa  
sudo apt-get update 
sudo apt-get install ubuntu-tweak
update-manager -d
sudo apt-get install update-manager-core
do-release-upgrade -d
sudo apt-get dist-upgrade

"Updating repository information

Third party sources disabled

Some third party entries in your sources.list were disabled. You can 
re-enable them after the upgrade with the 'software-properties' tool 
or your package manager. 
"


"
Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

 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.
