Alors que je m’appète à faire un serveur mail, en suivant ce tutoriel [https://www.tictech.info/post/mail\_preparation#toc0](https://www.tictech.info/post/mail_preparation#toc0) . Lors des premières étapes j’ai directement une erreur que j’essaye de résoudre, cela fait quelques jours… L’erreur est : apt install mysql-server ``` Reading package lists... Done Building dependency tree Reading state information... Done mysql-server is already the newest version. You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: mysql-server : Depends: mysql-server-5.5 but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). ``` Serait-ce une non-comptabilité du paquet, le tuto est en debian 7 alors que je suis en 8? PS: J’ai/avais une base de donnée en MariaDB En fassent apt-get -f install comme demandé dans le message d’erreur, une autre erreur intervient… > ``` > apt-get -f install > > ``` > ``` > Reading package lists...

apt-get remove --purge mysql-server mysql-common rm -rf /var/lib/mysql/\* rm -rf /etc/mysql/\* apt-get clean apt-get update apt-get dist-upgrade et tu re installe pour autant que tu n’aies pas mélangé les sources ---
