When I got o check for new updates in Update manager I get the following error. Any ideas on how I can fix it?

Could not download all repository indexes

The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.

Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/lucid/Release.gpg Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname)
Some index files failed to download, they have been ignored, or old ones used instead.
