Help with an error when software updater is run.

[cody7002002]

I just installed Ubuntu a few weeks ago, so there's a lot that I don't know. Today I went to run the software updater to see if there were any updates available and I received this message: "Failed to download repositor information" under details it says

"W:Failed to fetch http://ppa.launchpad.net/fioan89/slidewall/ubuntu/dists/quantal/main/source/Sources 404 Not Found
, W:Failed to fetch http://ppa.launchpad.net/fioan89/slidewall/ubuntu/dists/quantal/main/binary-i386/Packages 404 Not Found
, E:Some index files failed to download. They have been ignored, or old ones used instead."

How can I make this fix this so that I can run the updater as usual?

Hi

This guide tells you how to add sources to software-center.

Follow the steps but uncheck the sources that are giving you the problems. (the step before clicking the add button).

That should fix update-manager.
