Hi, I have two machines, both running Fedora Core 4. One is running yum 2.4.1, the other is running 2.0.3. When I try to do any updates on the other, I get the error message: "Insufficient server config - no servers found. Aborting.". The first machine works fine. I have even gone so far as to copy the yum configuration files from the first to the second machine, but no joy. I have tried disabling all of the repos files except the fedora.repo file, which contains: [base] name=Fedora Core $releasever - $basearch - Base baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/$releasever/$basearch/os/ mirrorlist=http://fedora.redhat.com/download/mirrors/fedora-core-$releasever enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora I have looked at the download.fedora.redhat.com URL with my browser and I see a repodata directory, so I believe the URL is correct. Does anybody have any good advice? Thank you Jeff Silverman
