sorry for being such a pain, but in order to get the most recent RPMs, i followed previous advice and ran # yum install fedora-release that seemed to work fine, /etc/redhat-release now shows Fedora Core release 0.95 (Severn) but when i tried to update yum with # yum update yum i got Gathering header information file(s) from server(s) Server: Red Hat Linux Null - i386 - Base retrygrab() failed for: http://mirror.dulug.duke.edu/pub/yum-repository/redhat/Null/i386/headers/header.info Executing failover method failover: out of servers to try Error getting file http://mirror.dulug.duke.edu/pub/yum-repository/redhat/Null/i386/headers/header.info [Errno 4] IOError: HTTP Error 404: Not Found apparently, the $releasever value in /etc/yum.conf is being replaced by "Null". what have i pooched here? rday
