Official package installer will not be far away, and I recommend you wait for it.
However if you dont want to wait, you can install unofficial copies I have built and uploaded to Github. If you install my unofficial copies, these wont have future automatic upgrade facility. To get Flightaware support and future upgrades, you will have to install official ones over unofficial packages when official packages are released. Please click here to see the How-To.
If you decide to install the unofficial version now and replace these by official packages from Flightaware later, then when installing official version, dont forget to first delete my repository from your Pi’s apt sources list by following command:
sudo rm /etc/apt/sources.list.d/abcd567a.list
sudo apt update
