Sou novo no ansible e estou tentando automatizar algumas etapas.

Esta tarefa é executada bem na primeira vez.

# Copy Root ssh keys within all devices
- hosts: etall
  tasks:
    - name: ssh keygen
      command: ssh-keygen -t rsa -f /root/.ssh/id_rsa -q -P ""

Na segunda vez, ele simplesmente trava depois de reunir os fatos. A configuração ANSIBLE_DEBUG=1mostra a etapa suspensa em:

16584 1554867575.39541: _low_level_execute_command(): executing: /bin/sh -c '/usr/bin/python /root/.ansible/tmp/ansible-tmp-1554867574.524454-229535370546451/AnsiballZ_command.py && sleep 0'

Durante o rastreamento na máquina cliente:

/usr/bin/python -m trace --trace /root/.ansible/tmp/ansible-tmp-1554873279.0459487-106888464136363/AnsiballZ_command.py

eu posso import base64depois/usr/bin/python

Isso não foi um problema durante a primeira execução. Também funciona após a reinstalação do sistema operacional na máquina cliente.

Versão:

ansible 2.7.6
  config file = /user/user1/plays/ansible.cfg
  configured module search path = ['/user/user1/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /user/user1/p363/lib/python3.6/site-packages/ansible-2.7.6-py3.6.egg/ansible
  executable location = /user/user1/p363/bin/ansible
  python version = 3.6.3 (default, Jul  8 2018, 21:13:48) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)]

A versão do Python na máquina cliente é 2.7.5

Trecho de saída detalhada logo após a coleta de fatos:
