Maybe a bit of assistance here? I have a newly-created installation of Buster. I want to install FA and attempted using this command:
wget https://flightaware.com/adsb/piaware/files/packages/pool/piaware/p/piaware-support/piaware-repository_5.0_all.deb which is found on this page: PiAware - dump1090 ADS-B integration with FlightAware - FlightAware
The error received is wget: unable to resolve host address … [the FA web site is listed but apparently new users are restricted from putting more than two links in a message.]
Suire looks like a DNS failure. However t here are no issues with DNS resolution on the pi or other computers on the network. Example: Pings are successful to numerous addresses no computer on this network has ever seen before.
Any thoughts? [This is hugely frustrating. It should not take half of a day to set up a feeder.]
