[Yum] No update since two or three months

[bertrand.arquilliere at free.fr]

Hello,

I send you an SOS about my Yum, i have no update since 2 or 3 months.
I have a Fedora Core 4 with the following :

[/etc/yum.repos.d] # uname -a
Linux tenebrae 2.6.17-1.2142_FC4 #1 Tue Jul 11 22:41:14 EDT 2006 i686 i686 i386
GNU/Linux

[/etc/yum.repos.d] # rpm -qa | grep yum
yum-2.4.1-1.fc4

Today, i ran rpm -e yum-2.4.1-1.fc4, installed a fresh yum found on rmpfind, ran
yum check-update, i had an update for yum, wich i installed, then :

[/etc/yum.repos.d] # yum check-update
Setting up repositories
Reading repository metadata in from local files

[09:55:26][root at tenebrae]

So i ran "yum clean all" and "yum makecache" and launched a new "yum
check-update" for the same output as above.

I also tried to had some repo in /etc/yum.repos.d, no change.

What can i do to have yum back on my system, i have no clue on what i can try
more.

Thanks for any help.

Regards.
