Setup Virtualbox on Ubuntu 16.04?

Virtualbox is a open source, well maintained virtual machine package that can install a huge array of x86 and amd64 operating systems

To install Virtualbox on Ubuntu 16.04 all you need to do is run this in a terminal:

sudo apt install virtualbox -y

Once this finishes installation you should be able to launch Virtualbox from your app launcher.

BTW I created a video version of this tutorial for a more visual feel

I recommend watching in 1080p60 and fullscreen! ^_^
