Install FlightGear in Ubuntu 14.04
There is a PPA available, but it contains the latest development snapshots for FlightGear, which now is 3.3 instead of 3.2 (shouldn’t be much more different than 3.2 though). To install the game from this PPA, type the following in the terminal:
sudo add-apt-repository ppa:saiarcot895/flightgear-edge sudo apt-get update sudo apt-get install flightgear
To run it type fgfs in the terminal.
You can also install the latest FlightGear release in Ubuntu using UbuTricks.
