I had the same problem with the same error message as kjacobs and tried to update manually and received the following error message...

E: Problem with MergeList /var/lib/apt/lists/repo.steampowered.com_steam_dists_precise_steam_i18n_Translation-en
E: The package lists or status file could not be parsed or opened.
