J'ai un problème avec l'installation de mysql que je ne peux pas résoudre seul. J'ai d'abord essayé de supprimer et de purger les anciens fichiers avec cette commande
sudo apt-get remove --purge mysql
J'ai aussi essayé
sudo apt-get remove --purge mysql*
Et
sudo apt-get remove --purge mariadb*
Les 3 commandes renvoient la même sortie ...
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
dbconfig-mysql : Depends: mysql-client but it is not going to be installed or
mariadb-client but it is not going to be installed or
virtual-mysql-client
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
Alors je lance ce qui m'est suggéré apt-get -f install
et j'ai
$ sudo apt-get -f install

Une autre chose que j'ai essayé était de supprimer mysql-server
puis de le réinstaller toujours la même erreur.
Quelqu'un peut-il aider avec ce problème .. Je suis à court d'idées comment puis-je le résoudre.
Mettre à jour la sortie de lsb_release -a
$ lsb_release -a

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
mysql-server : Depends: mysql-server-5.7 but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

lsb_release -a
sudo apt-get update
puis exécutersudo apt install mysql-server mysql-client
sudo apt install mysql-server mysql-client
Je ne sais pas pourquoi, j'ai essayé ces commandes pendant environ une heure jusqu'à ce que je viens de faire
puis cela a juste fonctionné avec apt install.
EDIT: En fait, maintenant je sais pourquoi. Il se peut que lors de l'installation, il essaie d'afficher l'interface visuelle en demandant "installer la version du mainteneur du package" et similaire, et le TERM par défaut sur certains serveurs Ubuntu n'est pas en mesure de servir cela, donc l'installation génère une erreur. L'utilisation de Xterm résout ce problème.
