Minimal installation of Ubuntu server 20.04 LTS

This tutorial will show you the simple steps of installing a modern Linux Distribution – Ubuntu server 20.04 LTS edition. Following most of the default options during the setup configuration for simplicity.

Here are some basic data from the default installation setup settings:

  1. Installed packages – ~582 occupying 11G of space.
  2. 3 partitions when using automatic patition layout – boot efi, swap and root.
  3. ext4 used for the root parition.

We used the following ISO for the installation process – Ubuntu 20.04 LTS (Focal Fossa):

It is a LIVE image so you can try it before installing it. The easiest way is just to download the image and burn it to a DVD disk and then follow the installation below:
