When I attempt to upgrade the Update manager shows a warning message stating "Your ubuntu release is no longer supported." Okay... Click "close" it never goes away. Locks-up the update manager and game over.

Next, try to update the software sources but can't do that either since it launches from the System > Administer > Software Sources and guess what? Needs sudo...

But like all good linux software I'm sure the program is buried in a folder somewhere waiting for me to find it through the all powerful terminal program.

Already commented out all Maverick Sources by hand but that didn't do the trick.

Now what?
