This is a Nextcloud bare-metal installation on an Ubuntu server tutorial.
The goal of this guide is to have no warnings in the admin center and the instance should get a perfect security score from the nextcloud security scanner.
There are two tutorials.
Normal one is nextcloud.md and nextcloud_behind_NGINX_proxy.md is if you want to run Nextcloud behind a NGINX reverse proxy.
Feel free to offer feedback, open up issues or pull requests.
