V2 greengrass deployment error in lifecyclemanager.GenericExternalService

Question

Hello everyone, I followed this guide to create a core on the cloud9 environment: https://greengrassv2.workshop.aws/en/chapter1_introduction.html  
Appart from some minor issues, everything went fine. However then I went on to turn a computer running an ubuntu server into a greengrass core. I installed awscli, and then followed the same guide, the first component, hello world, deployed just fine. But then when trying to deploy the publisher after that, I get this error:

The component is the exact same as the one I succesfully deployed on the cloud9 greengrass core. Does anyone have an idea where this error comes from?

Answer

Hi,  
  
In the provided logs, you can see that there was an error:

```
reason=Script errored in install, serviceName=com.example.Publisher, currentState=NEW}
```

What this means is that the `install` command in the recipe failed to execute.  
  
You can look in the log file for com.example.Publisher and it should tell you what it was doing.  
  
From the workshop link you provided, the install step does the following:

```
        "Install": "pip3 install awsiotsdk numpy"
```

Is pip3 installed on the device you are trying to deploy to? If not, then you'll need to install that on the device first.

Answer

I just new it had to be something annoyingly simple.  
Quite embarrassing this is.  
thank you Rob, you are correct.
