There are big wishes for Signal to adopt the perfectly working Flatpak. This will make Signal show up in the verified subsection of Flathub, it will improve trust, allow a central place for bug reports and support and ease maintenance. Flatpak works on pretty much all Distros, including the ones covered by their current “Linux = Ubuntu” .deb repo. To make a good decision, we need to have some statistics about who uses which package.
