GoodVibes is now on julinux.yellow-snow.net. To use it you need to connect with a graphical client that supports audio. I recommend X2Go from https://x2go.org/. X2Go is free and open source. It is available for Linux, Windows, and MacOS. If you use either Mate or Gnome Desktops, GoodVibes is available under the Internet -> Audio and Video menu.
As with debian and ubuntu, in the process of installing this I fixed some things missing from the meson build environment.
