Invalid components are AppStream components which do not even have the bare minimum of required metadata. So they either lack an id, valid type, name or summary. This is usually a bug only the distributor or the author of a package repository can fix, but in this case it's actually a GNOME bug, more specifically a gnome-software bug. If you look at `/usr/share/app-info/xmls/org.gnome.Software.Featured.xml` you can see that GNOME Software wants to extend possibly existing metadata with new information that it needs to show featured apps. Only that it doesn't tell AppStream that these components are not supposed to be new components, but rather metadata extensions to existing components. So AppStream things someone injected invalid metadata and complains. The solution is to mark these metadata extensions properly as "merge components" by adding the `merge="append"` property, like this: https://gitlab.gnome.org/GNOME/gnome-software/-/commit/bb7f58f5f88381857cd9b5dbe608e75d459873f1 This change was reverted twice by accident now at GNOME, so that's why we have this issue. It's fixed in Debian's gnome-software package though. Cheers, Matthias -- I welcome VSRE emails. See http://vsre.info/
