You might try going to
System > Administration > Software Sources
Click on the Updates tab and at the bottom is Release Upgrade
Change it to either Normal Releases or Long Term Support releases
Then close and go to
System > Administration > Update Manager and see if it's there.

Copy and paste this into your terminal.


sudo sed -i 's/karmic/lucid/g' /etc/apt/sources.list && sudo aptitude update && sudo aptitude dist-upgrade
