i am unable to upgrade to ubuntu 14.04 from 13.10 and i get this error that says Could not calculate the upgrade

An unresolve problem occurred while calculating the uprade
this can be caused by
*Upgrading to a pre-release virsion of ubuntu
*Running the current pre-release version of Ubuntu
*Unoffical 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 terminal

You seem to have installed the cinnamon package on Ubuntu 13.10. Unfortunately, that package is not available yet for 14.04. To upgrade to Ubuntu 14.04 LTS you'll need to either wait for a fix for cinnamon to be available or uninstall the package and then upgrade.
