I am trying to migratean existing RHEL 6 machine to Centos 6. I followed the instructions in https://wiki.centos.org/HowTos/MigrationGuide I run into problems: when I run yum upgrade then yum tries to access a repository rhel-6-server-extras-rpms and then fails. What can I do that yum no longer tries to access this repository? _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
