I am running 12.04 x86, but when I check the sources.list file, there is nothing in there that seems to reference anything i386 (but the error spits out 'i386' as part of the repo url). I think it has to do with my above setup, because I am choosing to run the latest software? I'm just not sure where to look to resolve this. sources.list isn't helping :(
