Impossible d'installer ou de supprimer MySQL

Aujourd'hui, j'ai donc installé MariaDB pour pouvoir me connecter via phpmyadmin, apparemment cela n'a pas fonctionné, je l'ai donc supprimé, réessayé comme quatre fois et j'ai échoué. A décidé d'aller avec MySQL Server à la place. Je n'ai pas pu l'installer après avoir supprimé MariaDB.

Voici ce que j'essaie de faire et les sorties:

shavit@dedi:~$ sudo apt-get install mysql-server

Je suis vraiment perdu en ce moment .. Google m'a dit que je devrais courir apt-get install -fmais c'est ce que j'obtiens:

Je suis un débutant avec tout ce qui concerne Linux et en particulier Ubuntu. Quelqu'un pourrait-il prêter main forte et m'aider? Très appréciée!

Je pense que le fait que vous ayez installé MariaDB a causé ce problème. Les configurations que MariaDB a mises en place ne fonctionnent pas exactement bien avec vanilla MySQL. Si vous deviez purger toutes les anciennes configurations et tout configurer à partir de zéro, cela devrait fonctionner. Notez cependant que cela supprimera vos bases de données actuelles! Sauvegardez toutes les données importantes.

Essayez d'exécuter la commande suivante pour réinitialiser et purger toutes les choses liées à MySQL:

sudo apt purge mysql-client-5.7 mysql-client-core-5.7 mysql-common mysql-server-5.7 mysql-server-core-5.7 mysql-server

Une fois cela fait, exécutez ce qui suit pour mettre à jour votre système et "nettoyer" le cache de votre package.

sudo apt update && sudo apt dist-upgrade && sudo apt autoremove && sudo apt -f install

Ensuite, essayez de réinstaller MySQL Server:

sudo apt install mysql-server

Cette erreur peut se produire lors de l'installation mariadb-serverprécédente mysql-server. Pour résoudre cette erreur, vous devez supprimer les répertoires /var/lib/mysql*et /etc/mysql*supprimer tous les fichiers de configurations et de dépendances, avant d'essayer de réinstaller MySQL.

sudo apt purge mysql-client-5.7 mysql-client-core-5.7 mysql-common mysql-server-5.7 mysql-server-core-5.7 mysql-server
sudo apt update && sudo apt dist-upgrade && sudo apt autoremove && sudo apt -f install
sudo apt install mysql-server
