Aiuto con l'installazione di Discourse usando la documentazione di Github?

You don’t need to install any software. Postgres, redis, ruby are in the container.

Did you install nginx? You don’t need that either.

I would recommend that your create a new droplet and start again. Follow the instructions. They say nothing about installing those packages.

Install Required software i.e. Postgres 10+, Redis 2.6+, Ruby 2.5+

What told you to install any of these? Because the instructions you linked didn’t.
