Hello,
You have a problem of MariaDB configuration.
The error is clear : Access denied for user ‘dolibarrdebian’
The user that you should have created there :
MariaDB [(none)]> CREATE DATABASE dolibarrdb character set UTF8 collate utf8_bin;
MariaDB [(none)]> CREATE USER dolibarr;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON dolibarrdb.* TO ‘dolibarr’@‘localhost’ IDENTIFIED BY ‘mypassword’;
Needs to be the same, that you enter in the database setup of dolibarr
