To my knowledge, no one has ever successfully packaged signal-desktop. Even the Flatpak build script just downloads the binaries from signal.org and unpacks the DEB file.
https://github.com/flathub/org.signal.Signal/blob/master/org.signal.Signal.yaml#L73 Same for the ebuild in Gentoo Linux. https://gitweb.gentoo.org/repo/gentoo.git/tree/net-im/signal-desktop-bin/signal-desktop-bin-7.67.0.ebuild For this reason, I refuse to install Signal desktop on my machines.
