Hello everybody,
I need your help. Iām a beginner, so please be patient. Iāll try my best.
A few weeks ago, I installed Nextcloud in a docker of OpenMediaVault on my Raspberry Pi. So this is the first update for my Nextcloud. OpenMediaVault is fine, so I think itās only Nextcloud which has a problem. What I have done:
Yesterday, I got the message that thereās an update for Nextcloud. I started the update on the web interface and everything was alright till the question āKeep maintenance mode active?ā
Because I wanted to use the web based upgrade, I chose disabling the maintenance mode. I was directed to the upgrade page and started the update.
Since then, Nextcloud is in the maintenance mode and I donāt know what to do.
According to other topics, I logged in as root via SSH and went to installation directory of Nextcloud. There I tried different things. For example:
- disabling the maintenance mode: sudo -u www-data php occ maintenance:mode --off
- asking for the server status: sudo -u www-data php occ status
- updating Nextcloud with the command line: sudo -u www-data php ./occ upgrade
But nothing worked, I got always the following error message:
An unhandled exception has been thrown: Doctrine\DBAL\DBALException: Failed to connect to the database: An exception occurred in driver: could not find driver in ā¦nextcloud/lib/private/DB/Connection.php:68
The entire message is much longer (62 lines), but I think this part is the important one.
I donāt know what is exacly the problem and what can I do. What can I do to finish the update? Or instead of that how can i get back to my working Nextcloud installation?
I hope you can help me. Thanks in advance for your help!
