Jellyfin install blocked by port 1900 conflict
fails during a custom install because port 1900 is reported as already in use. The setup is meant to point at the correct movie and TV show folders. The system is a clean Zorin install, and is the first app being installed.
That means the conflict may come from a system service or base setup, not from a long list of existing apps. The next useful step is to find what is using port 1900 and then change either that service or ’s settings.
