I had a look at both, Flatpaks and Snap. My impression is that both are not ready yet, as well as have one fundamental problem described in the answer here. It looks like the best way to create one package for all would be AppImages, because Canonical and RedHat are fighting really badly at the moment. In my opinion it would be better to create one packaging standard like .deb, .rpm or arch’s .tar.gz which could be used by any distro. .If Linux goes the way snap/Flatpaks are, then we would have many instances of the same library on every filesystem. Like on Windows. I always liked the way of sharing the library between all the programs.
However, I think I won’t do any Flatpak or Snap-pack before I am going on vacation
