I am running Ubuntu 12.04 and the update manager keeps requesting I do a partial upgrade to for Ubuntu 13.04 kernel headers and image. I only have notices to upgrade on long term releases. Are these kernel headers and image needed for Precise if not how to I get around/rid of them. I have no 13.04 software sources and I did not try to upgrade to 13.04.

what is the output of cat /etc/apt/sources.list | grep raring – Raja Aug 7 '13 at 14:57
Running that code does not have any output. – user182139 Aug 8 '13 at 1:50
well that means , your sources.list not consist of raring content. ok whats the output of sudo apt-get update – Raja Aug 8 '13 at 2:05
Sorry for the delayed response travelling. There is nothing unusual it just runs through the software sources updates what it needs. No errors or anything. – user182139 Aug 21 '13 at 3:53
You still getting such upgrade notification ? – Raja Aug 21 '13 at 5:02

Open in your terminal and type

sudo nano /etc/update-manager/release-upgrades

Then it will open a file and it looks like enter image description here

There place the prompt value as either lts or never.

No problem with never value because you will get notified by web automatically if any version released.

hope that helps.
