Flatpak packages for Teleport, an app to simply share files over the local network.
Teleport should work on all modern GNU/Linux distributions that have a recent version of flatpak, inlcuding Ubuntu, Fedora, Arch and others.
If you have GNOME Software (or another GUI app to install flatpaks), just download this file and open it in Software (your browser should offer to do that before downloading).
Otherwise you can also install it from the command line:
flatpak install --from http://frac-tion.com/teleport-flatpak/teleport.flatpakref
