[Yum] One problem solved, another cropped up

Hi Kevin,

1. rpm -ev yum

2. remove or rename /etc/yum.conf,
    and, for yum 2.1.x, the directory /etc/yum-conf.d

3. rpm -ivh <path to mounted fedora install cd>/Fedora/RPMS/yum\*.rpm

4. edit the reinstalled config file(s) to suit your needs.

if you don't have a CD just download the appropriate rpm manually
(for Fedora Core 2, I think you said) from, for example:
  
    http://ftp.freshrpms.net/pub/freshrpms/fedora/linux/2/yum/yum-2.0.7-3.1.fc.fr.noarch.rpm

Or you could just recreate the config file(s) - see for example:

     http://svn.rpmforge.net/svn/trunk/rpms/yum/yum-fd.conf

The Official version for Fedora Core 2 is yum.2.0.7,
or if you're feeling more confident, try the 2.1.x Branch, which is
nearly feature complete - thanks again seth!

But please do RRTFM (see rpm -q -d yum):

 man yum
 man yum.conf
