Dear Maintainer,
I have installed hoteldruid from the debain main archive (this package
is not listed in gnome-software if you don't install it, maybe because
of this bug) and it is reported as having a propietary license in
gnome-software. Its appstream metainfo file reports the AGPL-3+ license,
which is approved for debian main archive and OSI approved. The package
should be shown as having a free license.

hoteldruid doesn't show in the GNOME Software app because of these issues:

https://appstream.debian.org/sid/main/issues/hoteldruid.html

To be more specific, your app icon needs to be at least 64x64.

I suggest removing the .xpm icon since it's legacy and not needed any
more (although it shouldn't cause AppStream problems any more).

The most common license for AppStream metadata is CC0-1.0.

Once those issues are fixed in Debian (and you've waited a day or two
for Debian's metadata to be updated), I expect hoteldruid will show
correctly in the GNOME Software app.

Thanks,
Jeremy Bicha
