As you know, Kubuntu 12.04 came out recently. Since I want to upgrade from 11.10, I followed the instructions on this page. However, after completing the update all packages step and rebooting, I never got a notification letting me upgrade to 12.04. I have tried the update again many times, and I have rebooted after each upgrade, yet I have never gotten this notification.
Any help would be appreciated. Thanks!
