Hello,

NextCloudPi updated to version v0.64.7

`

I am getting the exact same errors on Debian testing (php 7.3) and Nextcloud 13.04 and 14.03. I had a stable working system until a few days ago and noticed my Nextcloud client was not working and discovered this problem. I disabled memcache.local in config.php to get nextcloud to work. I am still looking for a solution. If I run ‘sudo sudo -u www-data php occ status’ command from the command line, I still get php errors “{main}PHP Fatal error: Uncaught Doctrine\DBAL\DBALException: Failed to connect to the database: An exception occured in driver: could not find driver in /var/xxxxx/xxxxxxx/nextcloud/lib/private/DB/Connection.php:64”
I am lost as what to do.

I’m running exact same setup (debian testing + NC 14.03) with same error when trying to launch php occ files:scan.
All other aspects are working fine : web portal, linux desktop client, android client.

Hello,
I’m running Apache 2.4 and PHP7.3-fpm on Debian 9 (raspberry) and same as you, I can’t make Nextcloud work with “memcache.local” enabled !
Did you find a workaround ?

I’d be glag to know it !

Best regards
