*This guide uses apt repositories for installing and updating signal-cli. [Every time Tails starts it installs and if you are connected also checks for updates on additional software](https://tails.net/doc/persistent_storage/additional_software/index.en.html#index3h2) and brings Signal Desktop up-to-date. No manual updates via flatpak for Signal Desktop needed anymore. If you have used this guide previously before September 24th, 2025, follow all steps and optionally [removing older installation from this guide](#remove-older-installation-of this-guide) to free up space.*
