Signal only provides a script for .deb based distros on their official website. The flatpak is currently not ideal because it stores encryption keys in plaintext.
The provided link suggests an automated installation in a Ubuntu Distrobox including automated updates. Useful for every distro that does not natively support .deb packages.
They’ve recently released a beta of an AppImage https://community.signalusers.org/t/beta-test-the-signal-desktop-linux-appimage/73330
This is great, but sadly appimages don’t work on immutable desktops. But it’s very positive that they are providing that.
Appimages definitely work on Bazzite
Yes, you are right of course.
I have used sivlerblue, kinoite and bazite. Each one of them could run appimages. What are you using?
You are correct, one shouldn’t post while sick, sorry.
I have no clue why they’re not just adopting the existing flatpak that a majority of Linux users use
