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.
Last time I installed slack through flatpack I couldn’t send any files. Not through drag-and-drop, neither through the filepicker. The latter was just empty.
Downloading files from slack also had awfully weird side-effects.
Slack doesn’t have an apt repo, so I download debs and updat manually. Maybe once half-a-year.
If that’s the experience I’d get on my signal through flatpack, I’d also rather be downloading manually. And I’d even compile from source rather than deal with that flatpack stuff.
