Yum updates

[Timothy Beck]

Alright, I give..;-)
I installed YUM per instruction on the website,
http://www.fedoralegacy.org/docs/yum-rh9.php

And I'm getting a KEY error for installing rpm's.
warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 8df56d05
I've done as suggested about deleting and trying again and so on.

I have about 10 rpm's that need to be updated and I don't want to "get"
each one manually. Granted, nothing critcal but does anyone have any
ideas how to fix this issue?

Thanks for any help,

Tim
