I'm a Linux noob. I did "uname -a" per the instructions above and this is the result: Linux LenovoLinux 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:12:00 UTC 2013 i686 i686 i686 GNU/Linux". There are no i686 downloads. Can someone tell me which one to use? I'd guess one of the i386 but I want to make sure.
