1) You really want >> to add to the /etc/sshd_config, your single > truncates the file.

2) Don't sudo if you run as root.

Instead of reinventing the wheel start with a well-known template such as https://github.com/chef/bento and adapt in small iterations.

My general advice is when you run into problems, run with headless false, and --on-error≈ask, and known credentials and jump in to the instance/console etc and troubleshoot. Bringing up the console and doing normal sysadmin trouble shooting is usually the solution to these things.
