Nextcloud is a free/libre self-hosted cloud software that runs on a LEMP Stack. A lot like how Matrix is a self-hosted, much more private version of Discord, Nextcloud is a self-hosted alternative to services such as Google Drive and MEGA.
This section covers the basic installation and setup of a Nextcloud server; It is highly recommended to also follow the further configuration section to get a feature-full Nextcloud experience.

Skipping this step is normally what causes people to get errors on initial setup.
