Getting Started: Using Yum on FC2. Need help.

[XenoDave]

I have been all over the forums looking for some help and finding the right solution for using Yum on FC2.

Here is what I have:
Fedora Core 2
Plesk 7.5.4
Yum 2.0.7

Yum config:

[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
exclude=kernel*

[psa-7.5]
name=Atomic Rocket Turtle - $releasever - SW-Soft PSA 7.5 RPMS
baseurl=http://3es.atomicrocketturtle.com/atomic/psa-7.5/$releasever/

[base]
name=Atomic Rocket Turtle - $releasever - Base OS RPMS mirror
baseurl=http://3es.atomicrocketturtle.com/3rd-party/base/$releasever/

[updates]
name=Atomic Rocket Turtle - $releasever - OS Update RPMS mirror
baseurl=http://3es.atomicrocketturtle.com/3rd-party/updates/$releasever/

Attempted #1:
yum update yum because I saw that I needed to update yum 2.1.x or something higher.
However shows that 2.0.7 is current version?

Attempted #2:
yum update but i keep getting this error:

• [...]
  Resolving dependencies
  .....Unable to satisfy dependencies
  Package glibc-dummy-fedora-core-2 needs glibc-common = 2.3.3-27.1, this is not available.

Even (if I recall correctly) when I was using the Fedora Legacy.

Question:
Can someone tell me what I am missing or doing wrong?

Thank you in advanced.
