title: make it so vagrant doesn't run apt-get update automatically
body: <p>When I do <code>vagrant up</code> on a new machine it tries do a <code>sudo apt-get update</code> before it runs of the provisioning lines. It appears that the process still exists however.</p>
  
  <p>My Vagrantfile:</p>
  
  <pre><code>Vagrant.configure("2") do |config|
      config.vm.box = "scotch/box"
      config.vm.box_version = "1.5.0"
      config.vm.box_check_update = false
      config.vm.network "private_network", ip: "192.168.33.10"
      config.vm.hostname = "vagrant"
  
      config.vm.provision "shell", inline: &lt;&lt;-SHELL
          apt-get -y install pdftk
      SHELL
  end
  </code></pre>
  
  <p>The problem is that some of the APT repos are returning 404's. This is causing output to stderr which appears to be preventing the shell provisioner winds up not running. Doing <code>vagrant halt</code> and then <code>vagrant up</code> a second time seems to do the trick but I'd rather not have to do 3x commands when 1x could be sufficient.</p>
  
  <p>Anyway ideas how to disable this behavior?</p>
  
  <p>Here's the output when I do <code>vagrant up</code> after doing <code>vagrant destroy</code>:</p>
