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

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

Notes from Aaron Meurer's tutorial on the git workflow

Cloning and forking the repository

1. Clone the repository.

git clone clone-url

2. Fork the repo on GitHub to your personal account. Click the Fork button on the main repo page.

3. Add your fork as a remote. This remote will be named after your github username. Go to the fork of the user repository (e.g. https://github.com/username/xxxx - replace username with the GitHub username-), and copy the clone url as in step 1. cd to the clone from step 1 and run
