Even with GUI package managers that are integrated with flatpak, I'm sure you can untick any flatpak app you don't want to update, just like you can unselect any update for a normal package in Synaptic.
To update Lollypop flatpak app (its official name is org.gnome.Lollypop which is a mouthful) and its runtime, I use:
A runtime is the gtk+ or qt environment the app is running in. So to install flatpak lollypop in MX15 (running gtk 3.14), I installed gtk 3.24 runtime (I think) at that point in time. Right now gtk+ is at version 3.28 so I assume that if I ran a full update of flatpak lollypop, runtime will also be updated to 3.28.
To update the Lollypop flatpak app alone, I'll have to run the following command:
Code: Select all
flatpak --app update org.gnome.Lollypop
Since it runs fine right now, I couldn't be bothered to update either the app or the runtime.
If I use:
then yes, all installed flatpak apps and their runtimes are all updated.
