appstream.debian.org claims that scdaemon metainfo file is GPL-licensed, but it is CC0-1.0

[dkg]

https://appstream.debian.org/sid/main/issues/scdaemon.html says:

metainfo-license-invalid

But, debian/copyright for the source package says:

Files: debian/org.gnupg.scdaemon.metainfo.xml
Copyright: 2017 Daniel Kahn Gillmor <dkg@fifthhorseman.net>
Comment: This file is licensed permissively for the sake of AppStream
License: CC0-1.0

perhaps this is a mis-parsing of the debian/copyright file? or something else?

Quaoting the error message:

The metainfo file does not seem to be licensed under a permissive license. [...]

What matters is the software's metainfo file, or rather, what the file itself claims to be licensed under.
Looking into the metainfo file:

<component>
    <id>org.gnupg.scdaemon</id>
    <metadata_license>GPL</metadata_license>
[...]

Change the metadata_license license value to e.g. FSFAP (which is a tiny permissive license by the FSF for auxiliary files) or CC0-1.0 (if adding the license text doesn't bother you, AFAIK that's even included as default license in Debian now).

In any case, I think your debian/copyright file needs to be fixed too for that file ;-)

thanks for the pointer -- i'm the author of both debian/copyright and the metainfo file, but i'd missed the metadata_license entry when i relicensed the file to CC0-1.0. I'll fix this by changing metadata_license :)

I've also opened https://bugs.debian.org/907072 so that lintian might be able to catch more of these issues automatically.

Thanks for your work on appstream!

Oh, that is really great! Thank you!
