Ok, for this exercise you'll need a copy of Ubuntu Linux already installed on your PC. I chose Ubuntu because it's one of the friendliest Linux distributions available, as you will see in a moment.
sudo apt-get update, followed by Enter. If Ubuntu asks for your administrative password, type it, and hit Enter to continue.
sudo apt-get install dkms, and hit Enter; then type
Yand hit Enter to install the DKMS package.
