Installing Ubuntu VirtualBox Guest Additions 20.04

VirtualBox is a popular virtualization software that allows you to run multiple operating systems on a single machine. If you're running Ubuntu 20.04, installing VirtualBox is a straightforward process that can be completed using the APT package manager.

To install VirtualBox from the Ubuntu repositories using APT, follow these steps:

1. Open the terminal and update your package list by typing: `sudo apt-get update`

2. Install VirtualBox by typing: `sudo apt-get install virtualbox`

Note that the version of VirtualBox in the repositories may not be the latest and greatest. However, this method works whether you're using Ubuntu Desktop or Server.

Once installed, you can launch VirtualBox from the Applications menu or by typing `virtualbox` in the terminal.

Before creating a virtual machine, make sure you have the necessary resources:

* An OS image file (ISO) - This tutorial uses an ISO image of Windows 10 (32-bit). You will need to obtain a valid ISO file for your desired operating system.

* A minimum of 20GB of free storage space - Each VM you create needs its own storage. The amount of memory and storage you need will depend on how many VMs you create and what you plan to do with them.

* A minimum of 4GB of RAM - VirtualBox recommends at least 16GB for optimal performance.

Additionally, you'll need:

* An SSH client of your choice

* A user account with sudo privileges

This tutorial assumes that you've logged/SSH'd into your Ubuntu 20.04 system. If you use a non-root user, prepend `sudo` on each command in this tutorial.

In the next sections, we will explore how to increase VM's video memory (VRAM) to improve performance and install VirtualBox from Oracle's official repository. We'll also cover installing VirtualBox on Ubuntu 20.04 via APT.

With these steps, you should be able to successfully install and set up VirtualBox on your Ubuntu 20.04 system.
