This is what I get:
$ vagrant up
Bringing machine ‘default’ up with ‘virtualbox’ provider…
==> default: Box ‘centos/7’ could not be found. Attempting to find and install…
default: Box Provider: virtualbox
default: Box Version: >= 0
The box ‘centos/7’ could not be found or
could not be accessed in the remote catalog. If this is a private
box on HashiCorp’s Vagrant Cloud, please verify you’re logged in via
vagrant login
. Also, please double-check the name. The expanded
URL and error message are shown below:
