Fails while updating from Ubuntu 12.04 to 12.10

Asked by Malhar Anjaria on 2013-06-21

Following message appears while setting up new software channels:

An unresolvable problem occurred while calculating the upgrade:
E:Unable to correct problems, you have held broken 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
