This means that you are trying to import a key with a version of GnuPG that is too old to understand it.  That key uses a feature (called DSA2) that didn't exist in version 1.2.6 of GnuPG.

While you don't have to upgrade Linux on server 1, you do need to at least upgrade GnuPG.

Go to http://www.gnupg.org/download/ and grab the latest 1.4 version of GnuPG (at the moment, it's 1.4.13).  That is the easiest replacement for 1.2.6, and will handle that DSA2 key just fine.
