We don't plan to add Linux support ourselves at the moment but we'd love if someone contributed that. As was mentioned elsewhere it might be challenging to provide a bundle that works across different distributions so investigating the possible options would be an important first step.
An AppImage or Flatpak package would make a great starting point that works across distributions. Making Livebook more accessible to Linux developers would improve its adoption, as well as the adoption of Elixir, Phoenix, and Fly.io.
