Answer 1

You need to check couple of things:
I- boto is installed on the target host, where you need to download the file from s3:
sudo -H pip install boto
II- If this is remote host then use this format:
- name: Download xx tarball
s3:
aws_access_key: "{{ AWS_S3_ACCESS_KEY }}"
aws_secret_key: "{{ AWS_S3_SECRET_KEY }}"
bucket: xxx
object: folder/xx-commandline-4.0.3.tar.gz
dest: '/tmp/{{ xx_tarball }}'
mode: get
when: st.stat.exists == false
Note: when you export the AWS credentials, it work locally but not for the remote host, so you need to pass the credentials to the module so it will work for remote host.
Hope it might help you
