Yeah, there's nothing preventing someone from running the PDS server on other distributions. The installer just does a few convenient things for you (like install Docker, opens port 80/443 using ufw, etc) and we haven't added and tested support for other distributions.

There is a Docker compose file in the repo, and advanced users shouldn't have any problems running the code on another distribution or even without Docker if they prefer.

Advanced users can just view the installer script as documentation.
