Mark Shuttleworth, Founder of Ubuntu, said in an announcement that snap packages aren’t tied to a specific Ubuntu store.
He informed developers that they can develop their own stores for snap packages and more.
The announcement read:
Hi folks Since this question has come up a few times and the common answer keeps missing the point, let me have a go. The snap *format* is not intrinsically tied to a store. You can stand up a snap on a system regardless of how it arrived at that system. So the current store implementation is not particularly relevant, and would not be a good starting point. The simplest approach would be to focus on delivering a snap to a system over HTTPS. Since there are no complex dependency maps, you don't need the same sort of sophisticated infrastructure that APT or Debs or RPM do, you just need a webserver and wget. I think we should do this in the snap code itself so it is more obvious to people, because folks are hung up about the delivery of snaps from Ubuntu. I would not expect other distros to want to fetch snaps from Ubuntu unless there were useful snaps for them there, snaps could easily be served from Debian.org. In a sense, snaps are being punished for being ahead - of course there is a sophisticated store in Ubuntu, we've been doing mobile and IoT and commercial stores for several years. But that's no reason to denigrate snaps themselves, quite the opposite. Mark
