-\section{Option 1: native installation}
-
-Go to \url{https://ubuntu.com/#download}, download the Desktop edition
-and then follow the instructions.
-
-You don't have to replace your existing operating system completely.
-Just make some free space (at least 30 GB for Ubuntu and the labs
-we will run) and install Ubuntu alongside your existing system.

-\section{Option 2: using a VirtualBox virtual machine}
-
-In case you have to keep your existing operating system and
-dual-booting is not an option, another option is to download VirtualBox
-(\url{https://www.virtualbox.org/}) and download and use our virtual
-machine image from
-\url{https://f000.backblazeb2.com/file/bootlin-big-files/training/ubuntu-20.04-20200617.ova}
-
-You will still need something like 30 GB of free space to run all the
-labs comfortably.
-
-In Virtualbox, you just have to use {\code File -> Import Appliance}
-to create a new virtual machine from this image.

-In this VM, here are the credentials:
