OpenRadar not showing airports

[atcguy]

Hello,

I just downloaded OpenRadar, and ran the .jar file on Linux (Ubuntu). However when I search for any airports nothing appears. I've tried multiple times and I can't figure it out. Any help is appreciated.

Usually you type in your desired airport code, or a part of the name and a result list appears below. This list bases on the airports available in fgfs and should return something, as it comes with the installation. Does this work?
If so, click on the download button below. It will download the map data from FGFS map server.
