title: How to fix permission denied error when trying to install packages using Ansible?
body: <p>I'm trying to write a simple Ansible Playbook, please look at snippets below. Using Ansible 2.4.0.0, Ubuntu 17.04, Python 2.7.13.
  This is my first time using Ansible and Playbooks so please don't be too harsh. What am I doing wrong?</p>
  
  <p>playbook.yml</p>
  
  <pre><code>---
  - name: install packages
    hosts: dbservers
    become: yes
    become_method: sudo
    become_user: user
  
    tasks:
    - name: Update repositories cache and install "python-minimal" package
    apt:
      name: python-minimal
      update_cache: yes
  </code></pre>
  
  <p>hosts file</p>
  
  <pre><code> ---
   [dbservers]
   db ansible_host=127.0.0.1 ansible_port=22 ansible_user=user ansible_ssh_pass=pass ansible_become_pass=pass ansible_become_user=user
  </code></pre>
  
  <p>Command: <code>ansible-playbook -i hosts playbook.yml -vvv</code></p>
  
  <p>Command above returns following error: </p>

  <p>Edit: If I connect through SSH to the same machine I can manually update apt-cache and install packages using same user (using sudo). If I run command 'whoami' inside Playbook it returns expected result (user name). </p>
