juniper_junos_software安装了软件，但任务因“没有处理程序..”而失败。

Question

我正在尝试使用juniper_junos_software模块在SRX550上安装12.3X48-D70，虽然它成功安装并重新启动了设备，但任务返回失败，因为出现了"No handlers“错误。

攻略：

- name: Upgrade Juniper devices
  juniper_junos_software:
    host: "{{ inventory_hostname }}"
    local_package: "junos-srxsme-12.3X48-D70.3-domestic.tgz"
    reboot: yes
    version: "12.3X48-D70.3"
    user: user
    passwd: "{{ secret }}"
    port: 22
  ignore_errors: True
  register: junos_upgrade
  when: junos_before|success

详细输出：

该错误在设备启动重新启动并脱机后不久出现。对于任何其他juniper模块，我都没有这个问题。

我运行的是Ansible 2.4.2、junos-eznc 2.1.8、python 2.7.5，Juniper.junos角色是2.1.0

已经有人向Junos的开发人员报告了such problem，看起来您受到了https://github.com/Juniper/ansible-junos-stdlib/pull/361和https://github.com/Juniper/py-junos-eznc/issues/651错误的影响。

然而，这个修复存在于ansible-junos-stdlib的2.1.0版本(您已经有的版本)中，所以我不清楚这是同一个bug还是另一个密切相关的bug。

解决这个问题的最好方法是联系开发人员，在Github上报告问题，确认这是同一个bug还是另一个bug，并修复它。
