Just upgraded to 20.04, Focal Fossa, which uses Gnome 3.36, from 19.10. I also have two Snaps of Gnome installed, gnome-3-32-1804 and gnome-3-34-1804. It is unclear to me if these Snaps are actually in-use anymore or if anything is depending on them. I couldn't find anything about dependencies in the snap man page, either. Is this even a thing with Snaps? Do I have to be concerned about dependencies? I'm not actually sure of what installed these two, older Gnome Snaps, either, but I've been cleaning up older snaps because they are conflating with some of my apt-installed packages and the apt packages tend to integrate with the system better, for example respecting theme settings.
