Bonjour,
Tout d’abord je m’excuse si j’expose mon sujet au mauvais endroit.
Ayant installé Deconz je rencontre un problème, à priori de mise à jour de certains paquets, à cause de debian bullseye. L’erreur empêche ou pose problème lors de la mise à jour des autres plugins.
ci-dessous le log des dépendances Deconz.
Merci de votre aide précieuse.
