[ubuntu] Repository Error

I'm running 10.04 and it shows an error when I try to update.

Failed to fetch http://ppa.launchpad.net/mozillateam...86/Packages.gz 404 Not Found Some index files failed to download, they have been ignored, or old ones used instead.

Is there a problem with the repository, or do I need to remove this one?

Thanks for any and all help.

Hey all, first post :)

When I was brand new to Ubuntu, I downloaded some packages using the APT before fully understanding it. I'm not 100% sure what I did back then, but these packages are causing errors with the 'Software Updater' such that it simply displays an error message, and then closes (however, I am able to update my software using the command line).
