Why am I getting this error on Update Manager?

Asked by Melinda

I see a red triangle, with a red question mark on it, on bottom right hand panel. When I click on it or try to update manager it says the following Failed to download repository information

Check your Internet connection.

W:Failed to fetch http://ppa.launchpad.net/adamkoczur/gtk1.2/ubuntu/dists/natty/main/source/Sources 404 Not Found

You are using Natty and the repo doesn't support Natty:
http://ppa.launchpad.net/adamkoczur/gtk1.2/ubuntu/dists/

I suggest you remove it
