Trouble shooting files Berechtigungen

[Michael]

If no new folder can be created

Change ownership to root:
bash

sudo chown -R root:root /var/snap/nextcloud/common/nextcloud/data/

Verwende Code mit Vorsicht.
(This fixes the "owned by www-data" conflict reported in your error log)
Ensure correct folder permissions:
bash

sudo chmod -R 0770 /var/snap/nextcloud/common/nextcloud/data/

Verwende Code mit Vorsicht.
Run the scan command again:
bash

sudo nextcloud.occ filescan --all
