There is a bug in old versions of Vagrant that causes it to fail to download virtual machines (boxes) when you request them. Here's the error message that's being reported...

Bringing machine 'default' up with 'virtualbox' provider...
==> default: Box 'ubuntu/trusty64' could not be found. Attempting to find and install...
    default: Box Provider: virtualbox
    default: Box Version: >= 0
The box 'ubuntu/trusty64' could not be found or
could not be accessed in the remote catalog. If this is a private
box on HashiCorp's Atlas, please verify you're logged in via
`vagrant login`. Also, please double-check the name. The expanded
URL and error message are shown below:

URL: ["https://atlas.hashicorp.com/ubuntu/trusty64"]
Error:

Until Vagrant issues a proper update to fix this problem, you can workaround it by running this command in a Terminal window...

sudo rm /opt/vagrant/embedded/bin/curl

That solution comes from this StackOverflow article via @underscorefunk.
