on my system its under /var/www/nextcloud/config/config.php
why do they keep changing the location
What installation do you use? Snap, Docker, … ?
I think it is normal.
/var/www/: your webserver root (search your apache2/nginx installation)
nextcloud/: your nextcloud directory
config/: config directory
config.php: config file
It’s a proxmox Instant, I used the image you download from the ui
Currently having trouble getting my zfs mount routed to nextcloud, none of the folders show up in the user directory
