A safe starting point is "yum clean all", but sounds more like your mirror list is pointing to a server that is not available, has dropped CentOS, or changed the path. Check all the servers in your config files. I like to use a local mirrorlist and/or hand-configure nearby and fast mirrors with baseurl=... in the /etc/yum.repos.d/*.repo files. If you want more detailed help you need to supply more info on your configuration. Phil
