Update and Alter is not working

Answer 1

It is a very bad practice to modify system data directly instead of using SQL commands.

The solution is to use ALTER USER command (see https://mariadb.com/kb/en/alter-user/) instead of trying to modify a system view.

In recent versions of MariaDB user data is stored in mysql.global_priv table, mysql.user is just a complex view which aggregates information from mysql.global_prov.
