“的变体；Ansible LINEINFLE添加重复行“；

我试图让ansible在ubuntu中配置无人值守的升级。不幸的是，在多次运行角色时，我会得到重复的行

这是我的密码：

- name: apt | Configure unattended-upgrades
  lineinfile:
    dest: /etc/apt/apt.conf.d/50unattended-upgrades
    regexp: "{{ item }}"
    line: "{{ harden_linux_unattended_upgrades_settings[item] }}"
    state: present
  with_items:
      - "{{ harden_linux_unattended_upgrades_settings | list }}"

及

运行它的结果是，它第一次工作正常。每次之后，我都会得到这个结果，并且（奇怪的是只有一些）重复行：

changed: [cloud-host] => (item=^Unattended-Upgrade::Mail)
changed: [cloud-host] => (item=^Unattended-Upgrade::MailReport)
ok: [cloud-host] => (item=^Unattended-Upgrade::Remove-Unused-Kernel-Packages)
ok: [cloud-host] => (item=^Unattended-Upgrade::Remove-Unused-Dependencies)
changed: [cloud-host] => (item=^Unattended-Upgrade::Automatic-Reboot)
changed: [cloud-host] => (item=^Unattended-Upgrade::Automatic-Reboot-Time)

在文件末尾显示以下内容：

Unattended-Upgrade::Mail "john@doe.com";
Unattended-Upgrade::Mail "john@doe.com";
Unattended-Upgrade::Remove-Unused-Kernel-Packages "true";
Unattended-Upgrade::Remove-Unused-Dependencies "true";
Unattended-Upgrade::Automatic-Reboot "true";
Unattended-Upgrade::Automatic-Reboot "true";
Unattended-Upgrade::Mail "john@doe.com";
Unattended-Upgrade::Automatic-Reboot "true";
Unattended-Upgrade::Mail "john@doe.com";
Unattended-Upgrade::Automatic-Reboot "true";
Unattended-Upgrade::Mail "john@doe.com";
Unattended-Upgrade::Automatic-Reboot "true";
Unattended-Upgrade::MailReport "on-change";
Unattended-Upgrade::Automatic-Reboot-Time "2:50";

我看到很多线程都有重复行的问题，但我无法确定我的问题。特别是，我不明白为什么这似乎与

Unattended-Upgrade::Remove-Unused-Kernel-Packages

及

我只是看不出和其他线路有什么区别

---

编辑： 谢谢你非常有用的回答！这就是我的结局（我也改变了其他部分）：

及

你有：

    "^Unattended-Upgrade::Automatic-Reboot": 'Unattended-Upgrade::Automatic-Reboot "true";'
    "^Unattended-Upgrade::Automatic-Reboot-Time": 'Unattended-Upgrade::Automatic-Reboot-Time "2:50";'

第一个正则表达式

^无人值守升级：：自动重新启动

同时匹配：

无人值守升级：：自动重新启动

和

无人值守升级：：自动重新启动时间

因此，第二次，它执行以下操作：

• 匹配无人值守升级：：自动重新启动，不执行任何操作
• 匹配

  无人值守升级：：自动重新启动时间

  并将其替换为

  无人值守升级：：自动重新启动

• 由于不再有

  无人值守升级：：自动重新启动时间

  ，它会将其添加回去

现在，您有2个

自动重新启动

和1个

自动重新启动时间

对于

无人值守升级：：邮件

和

无人值守升级：：邮件报告

您可以通过匹配以下

“

Unattended-Upgrade::Remove-Unused-Dependencies

- name: apt | Configure unattended-upgrades
  lineinfile:
    dest: /etc/apt/apt.conf.d/50unattended-upgrades
    regexp: "^{{ item }}\\s"
    line: '{{ item }} "{{ harden_linux_unattended_upgrades_settings[item] }}";'
    state: present
  with_items:
      - "{{ harden_linux_unattended_upgrades_settings | list }}"

harden_linux_unattended_upgrades_settings:
    "Unattended-Upgrade::Mail": "{{ ubuntu_common_email }}"
    "Unattended-Upgrade::MailReport": "on-change" # later if working set to "only-on-error"
    "Unattended-Upgrade::Remove-Unused-Kernel-Packages": "true"
    "Unattended-Upgrade::Remove-Unused-Dependencies": "true"
    "Unattended-Upgrade::Automatic-Reboot": "true"
    "Unattended-Upgrade::Automatic-Reboot-Time": "2:50"

    "^Unattended-Upgrade::Automatic-Reboot": 'Unattended-Upgrade::Automatic-Reboot "true";'
    "^Unattended-Upgrade::Automatic-Reboot-Time": 'Unattended-Upgrade::Automatic-Reboot-Time "2:50";'
