Why does it say Mysql is MariaDB?

Question

MySQL

I need to use Mysql specifically in the project because MariaDB gives errors:

Migration 20160704155442 failed during Execution. Error An exception occurred while executing 'ALTER TABLE user RENAME INDEX fk_8d93d6492b19a734 TO IDX_8D93D6492B19A734':

When you try to install Mysql, it says that it's already installed, connect? MariaDB again.
How can I install Mysql and use MariaDB instead?

Debian 9

Answer 1

apt purge mariadb-server
apt install mysql-server

Answer 2

There is a suspicion that the problem is not in Mary, but in the code.
