Installing FlightGear on Linux ============================== Binary packages --------------- Several major Linux distributions offer FlightGear binary packages in their official repositories; this is usually the quickest and easiest way to install FlightGear, but may not be the latest version. There are also a number of unofficial repositories offering more frequently updated binary packages (some including development versions, which have the very latest features but are also more likely to have major bugs); see http://www.flightgear.org/download/main-program/ for details.
