I juste updated the repo and uninstalled some redhat packages : rpm -e rhnlib rhn-client-tools rhn-setup yum-rhn-plugin rhn-check rhnsd redhat-indexhtml redhat-lsb rpm -e --nodeps redhat-release-server-6Server rpm -hiv sl-release-6.0-6.0.1.x86_64.rpm rpm -e --nodeps redhat-logos rpm -hiv redhat-logos-60.0.14-1.sl6.1.noarch.rpm I did a test for yum reinstall \*, and saw that 565 out of the 623 packages were to be re-installed, so I didn't want to get into problems with a remote server, I left it that way. I will do a reinstall on a server I got at the office, and I'll report back.
