(Disclaimer: I don't work for Canonical, I just use Ubuntu for my work.) I think it will end up like so: * apt/dpkg will remain the base packaging software on desktop and server. They're well-tested and familiar. * flatpak will become the primary format for installing desktop software outside of repo. This'll be nice for some large open-source projects that cause grief for distro packagers, and will also give companies a single target for major Linux desktops. Flatpak is too narrowly-targeted to replace snap in all cases snap was designed for. * snap will become a mechanism for image-based application deployment, primarily IoT. * docker/lxd/whatever will be used to target immutable deployments, primarily servers.
