Hi all. > > It looks a bit like a broken /etc/apt/preferences file. Try > removing/renaming this and retry. Well .. maybe not 'broken' .. but just 'configured': on SL3/4 apt preferences file is setup to prefer SL3/4 'base' repository over add-on third-party ones. If user wants to change this I would suggest editing this file and setting up the desired preference order .. instead of removing it all together ..
