In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): ERROR 1524 (HY000): Plugin 'xxxxxxx' is not loaded Enter current password for root (enter for none): I've purged the install of mariadb and reinstalled. Same thing. Running 20.04.5 Ubuntu. I have run into this in the past but was able to fix it then covid brain set in and it's tuesday.
