Bonjour,  
J’avais MySql d’installer sur un container, et lors de la MAJ de ce conteneur de Debian 9 vers Debian 10, j’ai perdu l’application MySql.

Comment récupérer l’application, car lorsque je lance un apt-get install mysql-server, j’ai le retour suivant : Le paquet n’a pas de version susceptible d’être installée.

Merci d’avance.

Container ? Docker, Kubernetes, lxc ? as-tu regardé du côté de MariaDB ?

Bienvenue sur le forum !

Sinon, ne t’embête pas à savoir ce qu’il se cache derrière, et installe juste le serveur MySQL par défaut avec le paquet `default-mysql-server`. C’est celui que j’ai et il fonctionne très bien.

Il s’agit d’un container LXC sous Proxmox.

MySQL a été remplacé par MariaDB et ce n’est pas nouveau :

Effectivement, cela installe MariaDB-Server, mais malgré cela, impossible de lancer l’instance :
