aws.greengrass.SystemsManagerAgent Component install failing

Question

I have followed the workflow to install the systems manager agent component on Greengrass V2: 
https://docs.aws.amazon.com/greengrass/v2/developerguide/install-systems-manager-agent.html#create-ssm-service-role

The Install fails, when I look at my core device on the console > deployments > Status on this Device > Failed:

```
"FAILED_NO_STATE_CHANGE: NoAvailableComponentVersionException: No local or cloud component version satisfies the requirements. Check whether the version constraints conflict and that the component exists in your AWS account with a version that matches the version constraints. If the version constraints conflict, revise deployments to resolve the conflict. Component aws.greengrass.SystemsManagerAgent version constraints: thinggroup/OnWatch_UmpTest_Group requires =1.0.0."
```

Log output shows:

`Caused by: com.aws.greengrass.componentmanager.exceptions.NoAvailableComponentVersionException: No local or cloud component version satisfies the requirements. Check whether the version constraints conflict and that the component exists in your AWS account with a version that matches the version constraints.

Not quite sure what I am doing wrong. Core device is a Raspberry Pi4

Answer

Please review the requirements for running the component https://docs.aws.amazon.com/greengrass/v2/developerguide/systems-manager-agent-component.html#systems-manager-agent-component-requirements.

> A Greengrass core device that runs on a 64-bit Linux platform: Armv8 (AArch64) or x86_64.

Your Raspberry Pi 4 uses a 32 bit OS by default, so it is Armv7, not Armv8 (aarch64).
