In June of 2017 I upgraded my Ubuntu 16.10 (Yakkety Yak) LTS install to Ubuntu 17.04 (Zesty Zapus). In October of 2017 Ubuntu released 17.10. (Artful Aardvark). I had not needed to upgrade my Ubuntu 17.04 installation for a while, but I felt it was best to keep it up-to-date. I was also experiencing issues with it from day-to-day.

After having to piece together a VirtualBox Guest Addition installation method from some old articles, I decided to put together one for Security Onion 14.05.
