How to fix the "Unable to calculate upgrade" issue when upgrading from 12.04 to 12.10?

I've been trying to upgrade to 12.10 ever since it was released today but I keep meeting this error:

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

I've tried updating all the currently installed software, removing all the extra PPAs, downgrading the files installed from xorg edgers' ppa but I haven't been able to solve the problem.

I fixed mine by removing ppa packages I had installed using ppa-purge

I knew I needed to do this by checking the logs in /var/log/dist-upgrade/
at the end of the apt.log file youll see what was confusing it. In mine it was a video driver, and i was running several upgrades, so I did:

sudo ppa-purge ppa:ubuntu-x-swat/x-updates

sudo ppa-purge ppa:unity-team/staging

sudo ppa-purge ppa:webapps/preview

sudo ppa-purge ppa:nilarimogard/webupd8

sudo ppa-purge ppa:scopes-packagers/ppa

sudo ppa-purge ppa:glasen/intel-driver

the last one - the glasen driver - seems to have done the trick for me. Upgrade is now proceeding as normal.
