I’d love to see something like this happen - especially if it can make releasing for and supporting multiple Linux distros more feasible than it currently is.
The main issue right now is configuring the audio stack. Jack in particular seems to be a bit tricksy depending on which way the wind is blowing and the current phase of the moon…
Robin is correct that the latest master commit on GitHub requires SuperCollider
v3.9-beta - which I assume there’s no package for at this stage. However, if it’s possible to package apps using snap ion a similar way than macOS and Windows - it might be much easier to just increase the package size and ship with a SuperCollider binary in the release itself. Sonic Pi makes it pretty easy to do exactly that (and also for any of the other binary dependencies such as Erlang and Ruby).
