Ici mon disque chiffré est : /dev/mapper/nvme0n1p5_crypt

dois-je utiliser cette commande pour changer mon mot de passe ?

--> sudo cryptsetup luksAddKey  /dev/mapper/nvme0n1p5_crypt

(ajouter une clé)

--> sudo cryptsetup luksRemoveKey Disk /dev/mapper/nvme0n1p5_crypt

(enlever la clé en question)

ou bien faire --> "sudo cryptsetup luksChangeKey" mais askip c'est pas tres fiable (ca beug beaucoup)

Merci davance de votre aide

merci davance à tous

DOUBLON. On ferme. La suite là-bas. Et pour les questions concernant Debian, s'adresser à un forum Debain.
