Install Ubuntu 20.04

For this and the following labs, you need a (preferably clean) Ubuntu 20.04 LTS (Focal Fossa) installation (see below). There are plenty of installation guides and tutorials on the web (and, in particular, on YouTube).

Steps

Download the ISO image from ubuntu.com
Create a bootable USB stick
Boot from USB stick and install
- Install Ubuntu desktop (full erase)
- Install Ubuntu alongside Windows (dual boot)

Warning.

Partitioning can be tricky if you are installing Linux for the first time. There are plenty of guides for “dual-boot Ubuntu installation” alongside both Windows and OS X. In most cases, you would first need to shrink one of your partitions (e.g., in Windows) and create an “unallocated space” which will be used during the Ubuntu installation process; see, e.g., this guide.

Ask for help if you are unsure.

Ubuntu Setup

Once Linux is installed we need to update all the packages, to do so open a terminal (CTRL+Alt+T) and type

sudo apt update
sudo apt upgrade
sudo apt install build-essential cmake
