I've tried to update my DNS to 8.8.8.8 and 8.8.4.4 on piaware and on my router and I get the same error.

I previously fed to fr24, but had an SD card failure and reinstalled piaware (which is working and feeding to FA), but I cannot get the fr24 feeding to work.

Any help would be appreciated.

Install it as shown below:

wget http://repo-feed.flightradar24.com/rpi_binaries/fr24feed_1.0.41-0_armhf.deb  

sudo dpkg -i fr24feed_1.0.41-0_armhf.deb

Signup will automatically start at the end of installation.
If it dos not start automatically, use following command to start it:

sudo fr24feed --signup

.

Another solution for GPG Key issue is as follows:

sudo apt-get update --allow-unauthenticated  
sudo apt-get update --allow-insecure-repositories  
sudo apt-get -y --allow-unauthenticated install fr24feed
