Start by locating the existing Linux DEB packaging configuration and release workflow, then trace how the application artifacts are produced. Identify the corresponding packaging entry points for RPM and Flatpak and verify their outputs locally or in the release workflow. Done means installable RPM and Flatpak packages are produced alongside the existing DEB package.
