I'm having an annoying issue with Synaptic Package Manager on Linux Mint where it's just giving me Error 403 when I try to update the repository list. I can't figure out the source of the problem, because all the sources are current and up-to-date. I've even tried removing all the sources and adding one at a time, but I'm still getting the errors.Failed to fetch http://repo.steampowered.com/steam/dists/precise/steam/source/Sources  403
