[Observium] Access denied for user 'root'@'localhost' (using password: NO)

Hi. After trying to upgrade to Community Edition version 0.15.6 i cant update the database.

root@observium /# /opt/observium/discovery.php -h all MySQL Error: Access denied for user 'root'@'localhost' (using password: NO)

Have done this regularly, but it seems it lost its config on root permisions on the DB

I have different passwords on my root and root for MySQL

I have no problem logging in to the web admin for PHPMyAdmin with my Mysql password for root.

Any clues?

Is there a scipt for roolback?

Best regards Einar
