How to resume an interrupted Vagrant install

If your host computer goes to sleep during the Vagrant install and the install process hangs, first:

• Type control-C to kill the installation process.
• Remove any temporary files that Vagrant tried to download:
  • Type: cd ~/.vagrant.d/tmp. This navigates to the directory where Vagrant puts its temprary files.
  • Type: open .. (open followed by a space and a period character). This means “Open the directory I am currently in.” This should open a “tmp” directory in your Finder (on a Mac) or the “My Computer” thing in Windows.
  • Delete any files in that folder.
• Navigate back to your vm2015 directory. E.g. cd ~/Desktop/vm2015.
• Type vagrant up to restart the installation process.
