Data base Creation error


I try to install my Xibo server on ubuntu, but I have a problem when I create a database."Could not connect to MySQL with the administrator details. Please check and try again.

Error Message = [SQLSTATE [HY000] [2054] The server requested authentication method unknown to the client]"

I don’t why this message is here because I have the good password for the account root on mysql.

Can you help me please?

I would guess you’re using too new a version of MySQL. Versions 2.3.9 and earlier need MySQL 5.6. Versions 2.3.10 onward will work with MySQL 5.7. MySQL 8 isn’t supported.
