For MySQL 5.7.6 and newer as well as MariaDB 10.1.20 and newer, use the following command. The following command tested at mysql version 8.0.4 :

UPDATE mysql.user SET Password=PASSWORD('new_password') WHERE User='root';

UPDATE mysql.user SET PASSWORD FOR 'root'@'localhost' = PASSWORD('new_password');

UPDATE mysql.user SET PASSWORD=PASSWORD("new_password") WHERE USER='root';
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3  Changed: 3  Warnings: 0

6. After executing the SQL statement, flush the privileges to ensure the changes take effect. Exit the MariaDB server prompt by typing exit;:

MariaDB [mysql]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

MariaDB [mysql]> exit;

9. Save the configuration file and start the MariaDB server once more.
10. You should now be able to connect to the MariaDB server using the newly set password:

mysql -u root -p

It will prompt you to enter the password. Provide the password you set in step 5.
