Well, I’m just automating what people currently have to do manually : visit GitHub and download DEB and install DEB.
Yeah. You should never do that. Like ever. Build from source; or use a vendored tarball. https://wiki.debian.org/DontBreakDebian
.deb is a terribly insecure nightmare thats held up by the excellent debian packagers, gpg , and checksums, and stable release model. don't use .deb files.
