Vagrant's Ubuntu 16.04 vagrantfile default password
<p>I'm attempting to deploy and run an Ubuntu 16.04 VM via Vagrant 1.9.1.
The Vagrantfile I'm using is from Atlas:</p>

<p><a href="https://atlas.hashicorp.com/ubuntu/boxes/xenial64/" rel="noreferrer">Ubuntu Xenial 16.04 Vagrantfile</a></p>

<p>I'm using Debian Stretch as the host OS. Vagrant was installed via a .deb available from Vagrant's website.</p>

<p>The Vagrantfile does run and deploy correctly. I can ssh into the VM via both my host OS and using 'vagrant ssh'. However, I have one minor blocker when attempting to ssh in from outside.</p>

<p>The default user in this VM is named 'ubuntu', and looks to have a password set. However, I have no idea what the password is at all, and no docs seem to have the information that I'm looking for. Attempting to set a password via 'passwd' within the VM asks for a current password. Anyone see where this is going?</p>

<p>So my big question is this: has anyone else deployed this same Vagrantfile, and if so, does anyone know what the default user's password is?</p>
