Package: flightgear Version: 1:2016.2.1+dfsg-5 Tags: patch https://launchpad.net/bugs/1591115 reports that flighgear does not show up in GNOME Software, the default graphical software installer for Ubuntu 16.04 LTS and the next stable release of Debian (GNOME).
Upon investigation, I believe this is because appstream is confused because flightgear is not installing its app icons to the usual directories. I am attaching some patches to fix this and some other minor improvements. Thanks, Jeremy Bicha
