3.3 Obtaining the Ubuntu Installation Media

For the purposes of this chapter, the Ubuntu Desktop environment will be installed using the graphical installer. Begin, therefore, by downloading the Ubuntu Desktop 20.04 ISO image from the following URL:

https://ubuntu.com/download/desktop

The DVD ISO image is self-contained including all of the packages necessary to install an Ubuntu system and is named using the following convention:

ubuntu-<version>-<edition>-<architecture>.iso

For example, the Ubuntu 20.04 Desktop ISO image for 64-bit Intel/AMD systems is named as follows:

ubuntu-20.04-desktop-amd64.iso

Having downloaded the image, either burn it to disk or use the steps in the next section to write the media to a USB drive and configure your virtualization environment to treat it as a DVD drive.
