You can prefer local files over the distro-supplied data using: killall gnome-software gnome-software --prefer-local We prefer the distro-provided data for a few reasons: * the screenshots come from the mirrors, not upstream * we replace or add a few things to certain packages * it takes ages to stat and then load a lot of small files rather than slurping one large .gz blob. If you want to override the screenshot, you can either patch the .appdata.xml in the spec file like any normal file, or you can use the F22+ command in the spec file: appstream-util replace-screenshots /path/to/appdata.xml http://new-screenshot.png Hope that helps, Richard. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
