Hi, I took time to address this bug.
This bug report raise 2 issues: * Lack of hires support for icon * Lack of installation of document fils by debian-reference-common As for icon, tracing current ICON to make SVG or similar is needed. (Volunteer?) I will file another bug report on this and track it there. As for document files, bug submitter suggests tweaking dependency. But as I explained, that's wrong approach. Let's focus on this functional issue here first. As I used GNOME Software, I see some software UI lists "Add-ons". For example, "gedit" has many "bioSyntax", "Bookmarks", ... which install biosyntax-gedit, gedit-plugin-bookmarks ... If similar happens with debian-reference-common, lack of package installation issue raised by the bug reporter can be fixed. This lead me to read: * https://www.freedesktop.org/software/appstream/docs/sect-Quickstart-Addons.html * https://wiki.debian.org/AppStream/Guidelines * https://github.com/ximion/appstream-generator All these looks a bit too complicated for me but it looks like adding * /usr/share/metainfo/debian-reference-en.xml to debian-reference-en package * /usr/share/metainfo/debian-reference-fr.xml to debian-reference-fr package * /usr/share/metainfo/debian-reference-de.xml to debian-reference-de package * ... providing metainfo files with ADDON information may produce desirable list of packages to install. Let me work on it.
