Comment 1 for bug 253556

Thank you for taking the time to report this bug and help make Ubuntu better. However, this isn't a linux bug, so I'm removing that task. A 404 error suggests a network problem or a problem with the mirror that you are using to download your updates from.

Please could you try again in a few hours or select a different download source from System -> Administration -> Software Sources and then report back when downloading is successful.

Thanks
