I’ve recently added the AppStream metainfo file to an editor called Frescobaldi. This file is available in Fedora 32 since version 3.1.2-2.
This editor cannot be found in GNOME Software. I hoped that adding the metainfo file would have fixed this but it didn’t.
IIUC (but I may be wrong) GNOME Software relies on the metadata generated by the distro with appstream-builder and distributed by the package
appstream-data. But this package has not been updated for a month. I would expect metadata to be rebuilt if needed, or at least more often.
According to this message, metadata are built weekly. But it doesn’t seem true.
$ rpm -qa appstream-data appstream-data-32-6.fc32.noarch
I’m missing something?
I hope someone can shed a light on this topic, as I cannot find any information.
