I was trying to upgrade from 12.04 LT to 14.04 beta using update manager and using this command.
sudo do-release-upgrade --check-dist-upgrade-only --devel-release
But it is showing
Checking for a new Ubuntu release New release '12.10' available. Run 'do-release-upgrade' to upgrade to it
How can I skip the other versions and upgrade directly to 14.04 beta ?
