Warnings

asv-screenshot-no-media

A screenshot must contain at least one image or video in order to be useful. Please add an <image/> to it.

asv-desktop-app-launchable-omitted
org.gnome.PackageUpdater.appdata.xml -
This `desktop-application` component has no `desktop-id` launchable tag, however it contains all the necessary information to display the application. The omission of the launchable entry means that this application can not be launched directly from installers or software centers. If this is intended, this information can be ignored, otherwise it is strongly recommended to add a launchable tag as well.
