I have just instaslled dietpi 6.30.0 on my RPI3 model B. I wanted to test some things and I started with Nextcloud. The installation seems to work fine, and I can access to the login page of Nextcloud, but the default admin/dietpi account doesn’t work.
Is there any way to reset the admin user? I have tried to deinstall and reinstall nextcloud, but same problem each time.
