I am working on an implementation of LoRa architecture on RaspberryPi. So I am trying to install Chirpstack Gateway Bridge. But while installing Gateway Bridge as mentioned in the official website link I am getting this error:
root@raspberrypi:/home/pi/mqtt_demo_3# sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1CE2AFD36DBCCA00 Executing: /tmp/apt-key-gpghome.HwLDfOHwHV/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 1CE2AFD36DBCCA00 gpg: keyserver receive failed: Connection timed out
On exploring on web I found that the setup key provided by them is not working. Can we eliminate this error and how?
