Install Debian 13 (trixie)

Disable root account

Add normal user to sudo
Le mieux est de ne pas définir de mot de passe root lors de l'installation. Cela ajoute automatiquement l'utilisateur au groupe sudo.
Sinon après l'installation :

su  # log as root
apt update && apt install sudo # Installer la commande sudo
adduser $MY_SUBUSER sudo # Ajouter l'utilisateur au groupe sudo (chemin /usr/sbin/adduser). ou bien utiliser la commande `usermod –aG sudo $MY_USER`
su $MY_SUBUSER # log back to normal user. # se loger avec l'utilisateur

Disable root login
sudo nano /etc/passwd replace the shell path /bin/bash (or similar) with /sbin/nologin: root:x:0:0:root:/root:/sbin/nologin
