I have an Ubuntu-based PC and I want to turn it into a fully functional Odoo 19 server that is also reachable from the web. The work is in three parts: • Fresh installation of Odoo 19 Community on my local Ubuntu machine, including all dependencies, PostgreSQL setup, and configuration as a systemd service. • A small but important tweak to the Product module: only the attribute I choose and its sub-attributes must show on the product form; every other attribute set should stay hidden. • Full hosting setup so the same PC serves the instance publicly under my domain with SSL (Nginx reverse proxy, Let’s Encrypt, firewall rules, and any port forwarding that may be required). We will connect by remote session; once you are done I should be able to add a product, see just the selected attribute/sub-attribute fields, and load the site over HTTPS from an external network. Please include concise notes or a script so I can repeat the setup if needed.
