How can I fix a 404 Error using a PPA?

Every time I try to run update manager and check for new updates, this error message appears. Obviously this has some thing to do with the gnome3-shell I downloaded about a week earlier. Is these download links have been moved elsewhere or deprecated or something like that? Any Idea on how to fix this? Thanks in advance.
P.S :- I'm running Maverick Meercat
