Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

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!

I tried it, and it checked for a new version of Ubuntu, but it couldn't find any. I suppose that explains why the upgrade notification wasn't appearing. I've checked my software sources and found this, but I'm not sure if anything's missing or should be checked... –  A. M. Apr 29 '12 at 22:54

At this point, you don't need the -d on do-release-upgrade, because Precise is no longer a development version.

From the terminal, sudo do-release-upgrade should be sufficient.
