I discovered the reason for missing addons in GNOME Software by accident a few weeks back.
Apply those two patches to appstream-glib in Xenial, and the addons should appear: https://github.com/hughsie/appstream-glib/commit/ea8b160c8f05ae018dcf54181204cc5740c2aa1c https://github.com/hughsie/appstream-glib/commit/2c479053850958575c8de50fbee4433ec05019d3 (this only applies to AddOns which have AppStream metadata though) ** Also affects: appstream-glib (Ubuntu) Importance: Undecided Status: New ** Changed in: appstream-glib (Ubuntu) Status: New => Triaged ** Changed in: appstream-glib (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-software in Ubuntu. https://bugs.launchpad.net/bugs/1581775 Title: No option to (de)select add ons upon installation Status in appstream-glib package in Ubuntu: Triaged Status in gnome-software package in Ubuntu: Confirmed Bug description: With the Gnome Software Center (gnome-software 3.20.1+git20160426.1.a976144-ubuntu-xenial-0ubuntu1) the option to select or deselect certain additions disappears (as compared to the earlier Ubuntu Software Centre). Example of this would be additional gstreamer plugins with a media player install. This can lead to more bug reports due to less transparency (user has no clue what is being installed, main install fails because essential elements are missing) and potential bloat (software centre installs everything and the kitchen sink to make sure the install works). A return of an interface with choice options as with the earlier Ubuntu Software Centre seems preferrable.
