MarsSeed [1] filed a deletion request for lantern-beta [2]: I propose to delete this package, as the project no longer publishes beta releases/tags (since 2017). Also this package is broken now, as it just tries to download a DEB file from raw.githubusercontent.com master branch, but the downloaded file is a txt, not a Debian package.
