以下是剧本：

- name: Find "N-1" unpatching ID from the Yum History
  become: yes
  shell: yum history | head -n -3 | tail -n +5 | awk '{print $1}' | head -n +1
  register: unpatch
        
- name: Use expect module to unpatch the server to N-1 level
  expect:
    command: yum history undo {{ unpatch.stdout_lines }}
    responses: 
       'Is this ok \[y/d/N]\:"y"'

在第二个任务上运行此Playbook时出现的错误如下：

fatal: [linux-Server-x86-64]: FAILED! => {"changed": false, "msg": "argument responses is of type <type 'str'> and we were unable to convert to dict: dictionary requested, could not parse JSON or key=value"}

我试图对命令yum history undo ${ID}做出各种响应，但它要么在游戏中的任务级别卡住了，要么yum进程一直挂在系统中。

- name: Use expect module to unpatch the server to N-1 level
  expect:
    command: yum history undo {{ unpatch.stdout_lines }}
    responses: yes
