Rhooo, manque la moitié de mon poste ....
Pour faire un résumé j'avais amis un message d'erreur par rapport à mono, et pas d'accès à Emby ni impossible de faire les mise à jour.
Sur les conseils de Xavier (merci à lui) en faisant un aptitude update et aptitude upgrade, c'est passé, mais toujours pas accès à ipdemonserveur:8096
Dans mon terminal, avec la commande aptitude update j'ai une erreur concernant nginx et Emby (dernières lignes)
