title: Vagrant: PHP7.0-fpm.service failed because the control process exited with error code
body: <p>I have a new ubuntu/xenial64 box based Vagrant installation. Unfortunately the PHP7.0 service does not running</p>
  
  <p>If I running the following <code>systemctl status php7.0-fpm.service</code> command this will be the result:</p>
  
  <pre><code>ubuntu@Project-Yii-Shop:~$ systemctl status php7.0-fpm.service

  <p>The main problem that I tried to enable this service but the Vagrant Ubuntu ask for password and well, this Ubuntu in the Vagrant does not have any password. I googled on this problem but I saw this solution only and the above one.</p>
  
  <pre><code>ubuntu@Project-Yii-Shop:~$ systemctl enable php-fpm.service
  ==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-unit-files ===

  ==== AUTHENTICATION FAILED ===

  </code></pre>
  
  <p>So I do not know what I should do, because if I install PHP7.0 on a real Ubuntu server (not in Vagrant) I do not get this error.</p>
  
  <p>I use NGINX server with the following config:</p>
  
  <pre><code>location ~ \.php$ {
         include fastcgi_params;
         fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
         #fastcgi_pass   127.0.0.1:9000;
         fastcgi_pass unix:/var/run/php7.0-fpm.sock;
         try_files $uri =404;
     }
  </code></pre>
  
  <p>I use this command in the Vagrant file to install PHP7.0</p>
  
  <pre><code>apt-get install -y git nginx php7.0-curl php7.0-cli php7.0-intl php7.0-mbstring php7.0-gd php-imagick php7.0-fpm php7.0-mysql php7.0-pgsql php7.0-xml php7.0-zip
  </code></pre>
  
  <p>And this command run after the Vagrant is up in order to run php7.0 srevice.</p>
  
  <pre><code>service php7.0-fpm restart
  </code></pre>
  
  <p>Does anybody see any mistake?</p>
