Mounting VirtualBox shared folders on Ubuntu Server 18.04 LTS (Bionic Beaver)

This guide will walk you through the steps on how to setup a VirtualBox shared folder inside your Ubuntu Server guest.

Prerequisites

This guide assumes that you are using the following setup:

• Oracle VM VirtualBox version 6.0.10 with Extension Pack installed
• Microsoft Windows 7 SP1 as the host OS
• A fresh install of Ubuntu Server 18.04.2 LTS as the guest OS

You could still make this guide work with other setups (possibly with some modifications to the commands and whatnot).

.gitkeep

A .gitkeep file tells github to do the opposite of its default behaviour, which is to ignore empty folders.

If you want to track an empty folder, or a folder with untracked files, create a 0kb file with the .gitkeep file extension in that folder.

touch FOLDER_NAME/.gitkeep
