Well I did it. I did something incredibly stupid and now my repos are all hosed. Not that I'm a huge fan of Up2date, but I do like to use the notifier to keep me informed of new updates to the OS. Now that doesn't want to work. How do I recover the stock repos for FC3?
The only non-comment lines in /etc/sysconfig/rhn/sources on FC3 should be these four:
yum fedora-core-3 http://download.fedora.redhat.com/pub/fedora/linux/core/3/$ARCH/os/
yum updates-released-fc3 http://download.fedora.redhat.com/pub/fedora/linux/core/updates/3/$ARCH/
yum-mirror fedora-core-3 http://fedora.redhat.com/download/up2date-mirrors/fedora-core-3
yum-mirror updates-released-fc3 http://fedora.redhat.com/download/up2date-mirrors/updates-released-fc3
As an alternative to editing this file, you could reinstall the fedora-release package.
Paul.
