title: Vagrant error while mounting nfs shared folders following roots bedrock+trellis+sage tutorial
body: <p>Im following this repo <a href="https://github.com/roots/roots-example-project.com" rel="nofollow noreferrer">https://github.com/roots/roots-example-project.com</a>.
  I did all steps till the vargrant up to see the development part.
  It gives me this error after a few seconds:</p>
  <blockquote>
  <p>==&gt; default: Preparing to edit /etc/exports. Administrator privileges will be required... sudo: /etc/init.d/nfs-kernel-server: command not
  found</p>
  <p>==&gt; default: Mounting NFS shared folders... The following SSH command responded with a non-zero exit status. Vagrant assumes that this means
  the command failed!</p>
  <p>mount -o 'vers=3,udp'
  192.168.50.1:'/home/miguelrebola/projects/work/example.com/site' /vagrant-nfs-roots-example-project.com</p>
  <p>Stdout from the command:</p>
  <p>Stderr from the command:</p>
  <p>stdin: is not a tty mount.nfs: requested NFS version or transport
  protocol is not supported</p>

  <p>I need to get that going and i've tried everything i found on internet.
  It only gives this error once after that it only shows this when running vagrant up.</p>
  <blockquote>

  <p>==&gt; default: Checking if box 'ubuntu/trusty64' is up to date...</p>
