Raspberry Pi CM3+


I have already tested the gateway on a Raspberry Pi 3B+ and it works great, but I need to install it on a Raspberry Pi Compute Module 3+ (1GB RAM) that is running already an app and is connected to a display.

I can’t find any instructions on how to install the gateway on an existing Raspbian image without flashing image.
Can anyone be so patient to help me?

Thanks in advance.

You should be able to install the webthings-gateway-raspbian-buster-arm.deb package from here.

I have tried, but there are several dependencies missing, I have tried to install but got lost while trying. Can’t find a way to install everything’s needed.

What is missing? Are you running a standard Raspbian image? If so, is it based on Stretch or Buster?

I have used: sudo apt install filename

This is the output:

It seems like you’re on an older version of Raspbian. That package will only work on Raspbian Buster.

You always have the option of building the gateway yourself, by following the steps in the README.

The installed image is “Raspbian GNU/Linux 9 (stretch)”
