Note: It is highly recommended that you upgrade to the latest Raspbian Buster OS to gain the full benefits of PiAware
Execute the following commands from the command line:
wget https://de.flightaware.com/adsb/piaware/files/packages/pool/piaware/p/piaware-support/piaware-repository_4.0~bpo9+1_all.deb
sudo dpkg -i piaware-repository_4.0~bpo9+1_all.deb
This will download and install PiAware and required dependencies on your Raspberry Pi.
This will enable automatic and manual (web-based, via your request) PiAware software updates.
These updates are disabled by default. To leave updates disabled, skip this step.
