Hi Damage,
Welcome to our forums.
Please review our guidelines about how to ask for help, and provide us with some details about your issue, so we can help you solving it.
Are you getting any error message while performing the first step? If so, please share it with us. Also note that while in the tutorial the following command is the first step:
$ sudo apt-get install pamusb-tools libpam-usb
You don’t need to actually type the dollar sign (“$”), that just marks the command as to be executed as normal user.
