How can I upgrade rhel4 via yum? Short answer: it's not supported. While it can be done (I've personally done it several times in the past) it can only be considered as unsupported do-it-at-your-own-risk method. So unless you know how to maintain different versions of python, yum, and rpm, and fixing a "broken" system, I suggest you do it the "normal" way, using RHEL5 install CD. -- Fajar _______________________________________________ Yum mailing list Yum@xxxxxxxxxxxxxxxxx http://lists.baseurl.org/mailman/listinfo/yum
