Yum finds package in search but can't find it to install

Question

I got this issue on an FC8 server where if I search for something in yum, it finds the packages I am searching for but then when I go to install the package it says its not there...?

[hamstar@tankian ~]$ yum search pecl
php-pecl-apc.i386 : APC caches and optimizes PHP intermediate code

[hamstar@tankian ~]$ sudo yum install php-pecl-apc.i386
Setting up Install Process
Parsing package install arguments
No package php-pecl-apc.i386 available.
Nothing to do

[hamstar@tankian ~]$ sudo yum install php-pecl-apc
Setting up Install Process
Parsing package install arguments
No package php-pecl-apc available.
Nothing to do

wtf?

EDIT: Yum update shows this:

[hamstar@tankian ~]$ sudo yum update
Setting up Update Process
No Packages marked for Update

EDIT: I also tried this and tried it all again with no luck:

[hamstar@tankian ~]$ sudo yum clean all
Cleaning up Everything

EDIT: So i just realized this package is installed, but replacing the package name for pyqt (and variations of) which is not installed gives the same results. Here is the output for a package that is already installed on my other FC8 server.

[root@dolmayan ~]# yum install php
Setting up Install Process
Parsing package install arguments
Package php - 5.2.4-3.i386 is already installed.
Nothing to do

RESOLUTION
In Alex's comment down there he said go to this fedora wiki page so I did and followed the commands:

wget http://kojipkgs.fedoraproject.org/packages/fedora-release/8/6.transition/data/signed/4f2a6fd2/noarch/fedora-release-8-6.transition.noarch.rpm
su -c 'rpm -Uvh fedora-release-8-6.transition.noarch.rpm'

Got the key from here emptied the old gpg key and pasted the new one into it.

su -c 'echo > /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-8-and-9
sudo vi /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-8-and-9

Then I ran:

su -c 'rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-8-and-9'

Done!

Solution

I would start with:

sudo yum clean all

and then try

sudo yum -y install php-pecl-apc

The actual problem isn't search vs. install, but "running as user" vs. "running as root". As they can have different caches. You can also run with "yum search -v blah" to get a lot more info. (like the repository the package is in).

Yea I tried this too sorry, also didn't work...

[hamstar]

Thanks, I tried it but no cigar :(

[hamstar]

No luck with this either :(

I am recalling that F8 was affected by the signing key compromise a while ago, and you needed to update the keys. If it has been a while since you have attempted any updates on the box, I would make sure that you have the "fedora-release-8-6.transition" package installed (rpm -qa|grep release) And if not, check out fedoraproject.org/wiki/…

Oh it is installed, I was just using it as an example tho... replace php-pecl-apc with pyqt which is not installed and it does exactly the same, I've tried pyQt, pyqt, pyqt.i386 and pyQt.i386.

Updated question with output from a working yum install for a package that is already installed on my other FC8 box.

Running "yum list installed 'pecl'" is much better than using grep.
