I had a look at two of them, first tried atril but lacked the required
disk space to build it, so ended up building two smaller packages and
running 'appstreamcli validate-tree debian/<packagename>' to see what
the issue is.
It occured to me that I do not really need to build and test locally, I
can just have a look at <URL: https://tracker.debian.org/pkg/atril > for
the Appstream info, and sure enough, under 'action needed', there is a
link to
<URL: https://appstream.debian.org/sid/main/issues/atril-common.html >
listing one error and two warnings, gui-app-without-icon,
asv-cid-desktopapp-is-not-rdns and missing-launchable-desktop-file.
