As far as I know, Jamulus is not included in the official Debian repository.
Compiling Jamulus needs a bunch of dependencies (which in my case resulted in a GNOME desktop install on my server) which I rather want to avoid on my server.
It would be great if there were official Debian packages which are released via GitHub releases. These packages could be built automatically by GitHub Actions on every release.
We already have the necessary scripts in this repository, so it should be easy to implement.
