I am newbie to ansible. I am trying to execute two different task.
1. checking passwdless login. executing hostname and id command in the
remote host and printing its result when succcess.
2. executing ssh-copy-id and copying pub key to the remote host
I want to execute the second task, only if the first task failed.
Please let me know the mistake I am doing here.
