-# Ubuntu
-
-## OS Installation
-
-Download and boot the [latest Ubuntu release](https://releases.ubuntu.com/21.04/ubuntu-21.04-desktop-amd64.iso).
-
-Follow the steps with these customizations:
-
-![img1](img/ubuntu-installation/1.png)
-![img2](img/ubuntu-installation/2.png)
-![img3](img/ubuntu-installation/3.png)
-
-The partitioning is:
-
-1. 256 MB : EFI partition
-2. 20 GB : system partition
-

-![img5](img/ubuntu-installation/5.png)
-
-Remove the installation disk and then reboot.
-
-Skip the welcoming window.
-
-Don't install updates if Ubuntu asks to. The scripts will.
-
-## Admin access
-
-You can add your public SSH key to access the administrator account later:
-
-```shell
-unset HISTFILE
-sudo mkdir /root/.ssh
-sudo wget github.com/xpetit.keys --output-document !$/authorized_keys
-sudo chmod 400 !$
-```
-
-## OS configuration
-
-Run a terminal and type these commands:
-
-```shell
-unset HISTFILE
-sudo apt -y install git
-git clone https://github.com/01-edu/public.git
-public/sh/debian/ubuntu/setup.sh
-```
-
-The script will ask for student user password (which will be deleted after) and then after a long configuration process it will restart the computer.
-
-The system is now read-only, every data is written to a temporary partition.
-
-The session is password-less.
-
-To gain a superuser terminal, use SSH:
-
-```console
-user@remote:~$ ssh -p512 root@IP_ADDRESS
-```
-
-To gain access with read/write access to the filesystem, use this command:
-
-```console
-root@ubuntu:~# overlayroot-chroot
-INFO: Chrooting into [/media/root-ro]
-root@ubuntu:/#
-```
