@OldDxer:
The Flightaware package from apt repository is for RPi (arm7).
For PC (i386/x86/amd64), you need to build package from source.
J Prochazka has written script for doing this automatically.
Using this script, I have installed dump1090-mutability and Piaware data feeder on my PC running Ubuntu 16.04, but option to install dump1090-fa is also available in this script.
.
.
Here are the commands to downloads and run the script
sudo apt-get update
sudo apt-get install git
git clone https://github.com/jprochazka/adsb-receiver.git
cd ~/adsb-receiver
chmod +x install.sh
./install.sh
.
