Hello

I want to install Openstack but I'm having an error I don't really get.

Code: ERROR : Error appeared during Puppet run: 192.168.0.2_mariadb.pp Error: Could not prefetch mysql_user provider 'mysql': Execution of '/usr/bin/mysql -NBe SELECT CONCAT(User, '@',Host) AS User FROM mysql.user' returned 1: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

greetings
