There have been some questions with regards to setting up the LoRa Gateway Bridge and configuring the packet-forwarder to make it communicate with the Gateway Bridge. As an attempt to help you out, I’ve created a page with debugging steps: https://docs.loraserver.io/lora-gateway-bridge/install/debug/.
Looking forward to learn if this is helpful, steps are unclear or steps are missing.
In a nutshell, you will probably have to install those packages by yourself. The chirpstack-gateway-os-full image only provides you the tools that you need to deploy the Chirpstack ecosystem, tools being used for debug purposes are external, hence, that’s why are not included in the images.
