Thank you for the heads up.  The lintian test is using appstreamcli
validate-tree, and as far as I know this do not report any false
positives, but the same issues that would make the appstream parser
ignore the Appstream information.

Peter, do you have an example package I could look at to see the false
positives you are talking about?  The example fragments mentioned
earlier are confusing, as the lintian check should only run if a file is
discovered in /usr/share/metainfo/, and the message "I: ~:~:
dir-no-metadata-found" indicate that no metainfo XML file was present in
the directory.

Just as a test and to check, I fetched the source for a random package
listed on
<URL: https://udd.debian.org/lintian-tag/appstream-metadata-validation-failed?affected=yes >,
catfish, and its lintian detected Appstream error was present (W:
org.xfce.Catfish:~: metainfo-filename-cid-mismatch).  If there is a
false positive somewhere, I am happy to investigate.
