1. Ersteinrichtung

Wechsle als Erstes mit su - zum Root-Benutzer, installiere sudo und füge deinen Benutzer zur sudo-Gruppe hinzu:

BASH

su -

(Gib hier das Root-Passwort deiner VM ein)

Führe danach diese Befehle aus, um die Grundlagen einzurichten und das Skript korrekt auszuführen:

BASH

# 1. sudo installieren und Benutzer zur sudo-Gruppe hinzufügen
apt update && apt install -y sudo
usermod -aG sudo USER

(Hinweis: Damit die Gruppenzuweisung sudo für deinen normalen Benutzer USER nach dem Skript greift, einmal kurz per exit aus- und wieder einloggen.)

Install Script
