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?
