Hello, everybody. I would like to update my server. Since my database is too big for the normal process, I tried to update it via the command console with Linux. I unpacked the packages and wanted to do the update with the command:
sudo -u http /usr/local/bin/php56 -f occ upgrade
Only then does the error message appear
An unhandled exception has been thrown: exception ‘Doctrine\DBAL\DBALException’ with message ‘Failed to connect to the database: An exception occured in driver: could not find driver’ in /volume1/web/owncloud/lib/private/db/connection.php:54
Can anyone help me?
**Web server: NAS apache
**PHP version: 7.0
**ownCloud version: 9.1.8.2
**Updated from an older ownCloud or fresh install: Update (auf einem NAS von Synology)
