Hello,
I was on this page
http://docs.fedoraproject.org/yum/en/sn-using-repositories.html
It said:
Fedora Extras Repositories for Previous Versions of Fedora Core You must manually configure Fedora Core 3 systems to use Fedora Extras, using the instructions at http://fedora.redhat.com/projects/extras/.
The extras link didn't work.
