Here is how I resolve these issues:

  1. Check that the Greengrass daemon is running on the device. sudo systemctl start greengrass.

  2. On the PI run the top command before you start the deployment. As the deployment starts you should start to see python processes consuming more CPU. If you don't see this then your deployment isn't actually starting on the device.

  3. Examine the log files in /greengrass/ggc/var/log to check for any errors. There are both user and system logs. In the system logs you should see some evidence that something happened. That is, one of the files should have been updated around the time you started your deployment. You can then tail this file to see if there have been any errors.

I would suggest this as a starting point. If we can see evidence that the deployment started and potentially an error in one of those logs it will be possible to investigate further.
