Hi @starrago !

I got the same error (NoMethodError - undefined method underscore' for Seahorse::Util:Module) after installing the agent on my EC2 instance following these instructions:

https://docs.aws.amazon.com/codedeploy/latest/userguide/codedeploy-agent-operations-install-linux.html

I installed this version: releases/codedeploy-agent-1.0-1.1352.noarch.rpm

Could you solve this problem?

[asaf-erlich]

What ruby version are you using? What OS are you using? What gems do you have installed? I see in the logs at the end it says "not enough child processes running - missing at least 1 - respawning". Did the agent self-recover or did it stay dead?

Having the same issue on Linux:

Gem list attached. Is there any insight available as to what this long-standing issue could be?
