Those instructions look like they are for centos. Try: yum install yum-conf-epel
instead of wget/rpm Did you use yum install yum-conf-rpmfusion ----- Original Message ----- From: "Mahmood Naderan" <nt_mahm...@yahoo.com> To: scientific-linux-users@fnal.gov Sent: Thursday, January 2, 2014 2:39:35 AM Subject: Still having problem with epel Hi, Recently I have faced a problem with epel repository ad asked a question about that. That thread was messy so I decided to create a simpler scenario. I have followed the instructions from http://www.rackspace.com/knowledge_center/article/installing-rhel-epel-repo-on-centos-5x-or-6x and downloaded the rpm file. However the epel repository doesn't work for me. If I remove it, then everything is normal. Please see the commands # wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm --2014-01-02 11:07:27-- http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm Resolving dl.fedoraproject.org... 209.132.181.23, 209.132.181.24, 209.132.181.25, ...
