This is the snap for moonlight-qt, an open-source NVIDIA GameStream client.
It works on Ubuntu, Fedora, Debian, and other major Linux distributions.

Command-line Installation

sudo snap install moonlight

(Don't have snapd installed?)

That'll install the latest stable release of moonlight.

Or, if you're feeling adventurous, try the automatic builds available at the edge channel:

sudo snap install moonlight --edge
