Question

我使用ansible脚本在Amazon EC2和流浪盒中设置我的环境（Ubuntu）。然后我尝试在GermanVPS（Ubuntu Minimal）上设置相同的环境。使用Apt安装软件包似乎不起作用。

我跑

ansible-playbook -i ansible/live -u priidu ansible/caselaw.yml -s -vvvv --start-at-task="install"

会出现以下错误。

failed: [master] => (item=postgresql-9.4,postgresql-contrib-9.4,postgresql-server-dev-9.4,python-psycopg2) => {"failed": true, "item": "postgresql-9.4,postgresql-contrib-9.4,postgresql-server-dev-9.4,python-psycopg2"}
stderr: E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. 

msg: '/usr/bin/apt-get -y -o "Dpkg::Options::=--force-confdef" -o "Dpkg::Options::=--force-confold"   install 'postgresql-server-dev-9.4' 'python-psycopg2'' failed: E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. 


FATAL: all hosts have already failed -- aborting

然后我尝试

ansible-playbook -i ansible/live -u priidu ansible/caselaw.yml -s -vvvv --start-at-task="dpkg configure"

我收到以下错误消息

failed: [master] => (item=postgresql-9.4,postgresql-contrib-9.4,postgresql-server-dev-9.4,python-psycopg2) => {"failed": true, "item": "postgresql-9.4,postgresql-contrib-9.4,postgresql-server-dev-9.4,python-psycopg2", "parsed": false}

FATAL: all hosts have already failed -- aborting

那里发生了什么，我该如何开始解决难题？

编辑：我的剧本的相关部分

- name: dpkg configure
  shell: dpkg --configure -a

- name: install
  apt: name={{ item }} update_cache=yes
  with_items:
    - postgresql-9.4
    - postgresql-contrib-9.4
    - postgresql-server-dev-9.4
    - python-psycopg2

编辑2：添加了剧本命令。

编辑3：当我将RAM从64MB增加到512MB时，问题就消失了。

Answer 1

当我尝试通过ansible-playbook安装docker时遇到了这个问题。

我尝试将RAM从512Mb增加到1024Mb。但它没有用。

然后我找到了解决方案如下：

删除/ var / lib / dpkg / updates中的所有文件，然后重试!!

无论如何它对我有用！

Answer 2

我添加了一些任务来消除Ubuntu 16.04的dpkg问题，并且效果很好

tasks:
- name: configure dpkg 1
  command: sudo rm /var/lib/apt/lists/lock
  become: true

- name: configure dpkg 2
  command: sudo rm /var/cache/apt/archives/lock
  become: true

- name: configure dpkg 3
  command: sudo rm /var/lib/dpkg/lock  
  become: true

- name: configure dpkg 4
  command: sudo dpkg --configure -a
  become: true

- name: Update and upgrade apt packages 
  become: true
  apt:
    upgrade: yes
    update_cache: yes
    cache_valid_time: 86400 #One day

Apt安装与ansible
