How to Use Yum

Yum is a program / utility that is designed to keep your Fedora computer current with the latest patches and updates. Once your Fedora PC is configured, it is a good idea to regularly run Yum.

To get Yum to work:

1. Download yum for your package. I am on FC3 so I went to the following:

http://mirrors.kernel.org/fedora/core/3/i386/os/Fedora/RPMS/

2. installed yum by issuing the following command:

rpm -ivh yum*.rpm

3. import PGP key

rpm --import /usr/share/rhn/RPM-GPG-KEY-fedora

Note: on later distros, the above command won't work. Use this one instead:
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*

4. run: yum update

5. reboot
