You did an update, so it seems the likely cause is that yum may have created a .rpmnew file for your yum.conf instead of replacing it. Possibly the same happened with files in /etc/yum.repos.d . You need the new yum.conf and the new /etc/yum.repos.d/*.repo files to use yum on the new distribution. You may want to do a download of the yum rpm file (or use the one on your install CD/DVD) then do a "yum erase yum" or an "rpm -e yum". After that completes do an rpm reinstall of yum to get all the new yum.conf and .repo files
