After upgrade PHP5.5.9 to 5.6.29: An exception occured in driver: could not find driver' in /var/www/nextcloud/lib/private/DB/Connection.php

[nodje]

I was running 9.0.50 with php 5.5.9
I wanted to upgrade to latest 11.0.0
I had to upgrade to PHP 5.6.29 to be able to perform the upgrade.

upgrade to 11.0.0 and 10.0.2 failed with exception
An exception occured in driver: could not find driver' in /var/www/nextcloud/lib/private/DB/Connection.php

When I reverted my 9.0.50 backup and tried to put it off maintenance mode I got the same exception.

I can't run any occ command anymore.

Steps to reproduce

1. put in maintenance mode
2. upgrade PHP from 5.5.9 to 5.6.29
3. run any occ command

An exception occured in driver: could not find driver' in /var/www/nextcloud/lib/private/DB/Connection.php

This indicates, that the required driver is not installed anymore. Please make sure that the sqlite PHP module is loaded.

I will close this because it is an setup issue. For further questions please open an thread in our forums: https://help.nextcloud.com/
