Enabling flash in Fedora 18.

This is going to be a very terse post because of how critical it is. Flash is essential to the life of any computer user that is heavily media-centric, and not having it around could cause problems for Fedora's prolonged installation. Unfortunately, the clucks at Fedora thought that shipping a broken GPG checking system was acceptable, so this can be a lot harder than it has to be. These steps and commands will allow you to install Flash (and any other software) in Fedora 18.

The steps

su -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-18.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-18.noarch.rpm'

sudo yum install flash-plugin

This is by far the easiest way to 

go about the installation. What those

 two commands do is enabled a third-party

 repository named rpmfusion, and then install

 a package from there called flash-plugin that

 will integrate with Firefox.
