I have updated mysql-server(5.7 to 8.0) with this command : 

apt-get install mysql-server

And after the install , I get this error :

Job for mysql.service failed because the control process exited with error code.
    See "systemctl status mysql.service" and "journalctl -xe" for details.

Log journalctl -xe : 

-- L'unité (unit) mysql.service a commencé à démarrer.
