Owncloud error upgrading to v0.29

While upgrading to the latest version everything went swimmingly until the owncloud section where I received the following error message:

FAILED: sudo -u www-data php /usr/local/lib/owncloud/console.php app:disable firstrunwizard

An unhandled exception has been thrown:
Doctrine\DBAL\DBALException: Failed to connect to the database: An exception occurred in driver: SQLSTATE[HY000] [14] unable to open database file in /usr/

At that point, there is a whole bunch of lines and then install aborts. How can I fix this please?

From which version of MiaB are you upgrading?

I am upgrading from 0.28 to 0.29.
