Use Universalx64.1.0.0.4648.tar. This package covers all of the supported Linux distros *except* RHEL 4 and SLES 9, which are really old and required us to create a separate package.
Also, we would recommend that you pick up the ConfigMgr Linux clients for 2012 R2, even if you are still running 2012 SP1. You will still want the "Universal" package. And note that the version number on the R2 package (4580) is less than
the version number on the SP1 package (4648). This is confusing but correct -- the 4580 package is later.
