I have configured flathub in my debian 10 machine. However, gnome-calendar 3.32 does not show up in gnome-software. What show up is version 3.30.2 called Agenda. So I installed it via the command: flatpak install flathub org.gnome.Calendar And with flatpart list, I checked that it is indeed version 3.32 installed. But then, there is no launcher in gnome-shell. So I ran it with: flatpak run org.gnome.Calendar Then I went in the about dialog, and Calendar identifies itself as version 3.30.1, although the copyright is 2012-2019, so it is really 3.32.
