Bonjour

Pour pouvoir installer le paquetage `firmware-misc-nonfree`  
lance d’abord la ligne de commandes suivante :

```nohighlight
sudo sed -i 's/^\(deb.* main$\).*/\1 contrib non-free/' /etc/apt/sources.list

```

et ensuite celle là :

```nohighlight
sudo apt update && sudo apt install firmware-misc-nonfree

```
