Comment réparer l'installation d'un package corrompu (mysql)

Après la mise à niveau vers Ubuntu 16.04, j'ai remarqué que mysql avait des erreurs époustouflantes. Convaincu, c'était une configuration cassée, j'ai essayé de lancer une purge de mysql. Cela ne semblait pas tout supprimer, alors j'ai essayé de le faire moi-même:

sudo rm -r /etc/mysql
sudo rm -r /usr/share/mysql-workbench
sudo rm -r /usr/share/mysql
sudo rm -r /usr/share/mysql-common

C'était une erreur. N'essayez JAMAIS de le faire. Maintenant, mysql ne s'installera même pas correctement. J'ai essayé de réinstaller les dépendances:

sudo apt-get install --reinstall $(apt-cache depends mysql-server | grep -Po 'Depends:\s+\K[^ ]+$' | tr '\n' ' ' )

Et les packages eux-mêmes:

sudo apt install mysql-workbench mysql-server --reinstall

Mais je reçois toutes sortes d'erreurs cryptiques, telles que:

sudo apt-get install --reinstall mysql-server

Apt est-il incapable de récupérer d'une installation partielle? Dois-je réinstaller le système d'exploitation?

Procédez comme suit pour nettoyer les packages cassés:

sudo apt-get clean
sudo apt-get update
sudo dpkg -r mysql-client-5.7
sudo dpkg -r mysql-server-5.7
sudo dpkg -r libmysqlclient20:i386
sudo dpkg -r libmysqlclient20:amd64
sudo dpkg -r libmysqlclient18:amd64
sudo dpkg -r mysql-common
sudo dpkg -r mysql 

Après cela, réinstallez-le avec:

sudo apt-get install mysql mysql-client* mysql-server*

Merci à @Videonauth

sudo dpkg -r mysql-client-5.7
sudo dpkg -r mysql-server-5.7
sudo dpkg -r libmysqlclient20:i386
sudo dpkg -r libmysqlclient20:amd64
sudo dpkg -r libmysqlclient18:amd64
sudo dpkg -r mysql-common

Puis en cours d'exécution:

sudo apt-get purge mysql\* mariadb\* libmysql\* libmariadb\*

Si quelque chose échoue, exécutez simplement sudo dpkg -r <failedpackage>et si cela échoue, supprimez simplement le package qui en dépend. Si vous répétez, apt-get finira par fonctionner à nouveau.

Essaye ça,

exécutez cette commande pour purger mysql, remplacez la version 5.7 par votre version installée

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

exécutez ceci pour nettoyer et mettre à jour les packages

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

enfin installer mysql

sudo apt install mysql-server

cela a fonctionné pour moi.

Après avoir purgé mysqlcomme indiqué ci-dessus, vous devez installer mysql de cette façon:

sudo apt-get install mysql-common 
sudo apt-get install mysql-server

Lorsque vous installez de cette façon, vous n'aurez pas d'erreur d'installation.

Je ne connais pas la raison exacte, mais toutes ces méthodes n'ont pas fonctionné pour moi. Dans mon cas, la procédure qui a corrigé le problème était:

sudo apt-get purge mysql-*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get dist-upgrade

sudo rm -rf /etc/mysql
sudo rm -rf /var/lib/mysql*

et redémarrez !

enfin, j'ai pu courir sudo apt-get install mysql-server!

Cela a fonctionné pour moi

sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get dist-upgrade

puis après j'ai réinstallé mysql avec

sudo apt-get install mysql-server et maintenant ça marche bien.

La commande sudo dpkg -r ne fonctionne pas pour moi ..

J'avais l'habitude sudo apt-get purge mysql-*de désinstaller tout le pageage relâché puis de les réinstaller
