Hey @ehd - the previous script is not up to date. I updated it to have all the goodies we seem we might need for this course, you can find the script here. It should bring your machine up to speed starting from fresh installation of Ubuntu server 16.04 LTS.
It also comes with an update notebook for lesson one that should work on your local machine (I only tested this on AWS p2 and p3 instances) and it will also pull and unzip the dogs vs cats dataset used in the first lesson.
Good luck with the setup!
