I had a look, and in debian/control of <URL: https://salsa.debian.org/debian-astro-team/indi-armadillo-platypus.git > there is only one binary package listed. Which other packages are you talking about?
Note, to validate the appstream content you can use this oneliner after building the package: appstreamcli validate-tree --no-net --explain debian/indi-armadillo-platypus -- Happy hacking Petter Reinholdtsen
