hi, i know c6 it is not released, but centos-release packages was not upgraded when doing upgrade from 5.6 to 6.0 (using upgradeany option). [root at server Packages]# rpm -Uvh centos-release-6-0.el6.centos.5.x86_64.rpm warning: centos-release-6-0.el6.centos.5.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID c105b9de: NOKEY Preparing... ########################################### [100%] package centos-release-10:5-6.el5.centos.1.x86_64 (which is newer than centos-release-6-0.el6.centos.5.x86_64) is already installed i assume this was not tested because this upgrade method is not supported by upstream vendor. br ul -- Ulrich Leodolter <ulrich.leodolter at obvsg.at>
