我正在本地VM上运行一个大型ansible剧本以进行测试。我已经尝试了使用由vagrant提供的VM（使用https://app.vagrantup.com/geerlingguy/boxes/ubuntu1604）和使用Ubuntu Server 16.04手动创建的VM。在这两种情况下，在运行apt时通常会失败
apt:
upgrade: dist
update_cache: yes
和
apt:
name: nginx
state: present
update_cache: yes
给出错误400，例如：
E: Failed to fetch http://gb.archive.ubuntu.com/ubuntu/pool/main/j/jbigkit/libjbig0_2.1-3.1_amd64.deb 400 Bad Request [IP: 91.189.88.161 80]
我已经围绕该主题进行了很多搜索，但还没有提出任何建议。
我可以成功ping通IP，但是登录并手动运行sudo apt-get install nginx也会失败：

我认为这不是与ansible相关的问题，而是网络/防火墙问题。
您要回答的问题：
91.189.88.161？似乎resolv.conf文件中设置的解析器地址阻止了连接。将其设置为8.8.8.8即可解决。

使用until / retry组合：https://docs.ansible.com/ansible/latest/user_guide/playbooks_loops.html#do-until-loops
示例：
- name: Install packages
become: true
apt:
name: [packages]
update_cache: true
cache_valid_time='{{ apt_cache_valid_time|d(3600) }}'
register: apt_result
retries: '{{ apt_retries }}'
delay: 10
until: apt_result|success
tags:
- apt
- install

您可以在VM上访问Internet吗？尝试：
wget http://gb.archive.ubuntu.com/ubuntu/pool/main/j/jbigkit/libjbig0_2.1-3.1_amd64.deb
如果这不起作用，则说明您存在互联网访问问题。
答案 3 :(得分：0)
错误已清除400 Bad Request
E：无法获取http://gb.archive.ubuntu.com/ubuntu/pool/main/j/jbigkit/libjbig0_2.1-3.1_amd64.deb 400错误请求[IP：91.189.88.161 80]
URL正常。从命令行运行：91.189.88.161 80
# apt update
# apt install nginx
如果这可行，那么这可能是一个Ansible问题。
