Forgot to add, here's the relevant github issue for making your voice heard about appimage release: https://github.com/haveno-dex/haveno/issues/270
You don't really need to install it. Extract the deb and then extract the data archive. You can then run bin/haveno
I wasn't aware of that, will take a look. But the original request still stands.
Does deb come with the java dependencies packed together? Because, this is one of the advantages of am appimage, the enduser doesn't have to hunt down the dependencies.
AppImages are better than .debs, but still have basically full access to your userspace. flatpaks have a permission system, can be built with very strict permissions and the you can modify those as you see fit, e.g. through the Flatseal graphical interface. I would much more prefer a Haveno (universal or Reto) flatpak.
