When running on OSX, all is well. When running on Ubuntu, the following error is displayed:

Is there something with linux and traps that require a different definition than is present in https://github.com/elastic/examples/blob/master/Cloud%20Enterprise/Getting%20Started%20Examples/aws/terraform/ansible-install.sh#L4-L10 ?

I'm running into the same error but with the gcp/terraform version. Did you find a solution?

EDIT: The problem was me running terraform in a docker container that used Bourne sh instead of bash. All I needed to do was add bash as the interpreter.
