anchor.diff:  Sometimes networks fail or mirror sites go down. If you experience a failure, you can attempt to resume the construction by issuing `vagrant provision` at the command line.  Vagrant will attempt to start over, but will skip any provisions that have already taken place.
   
   === Cannot Acquire Repository Lock
  -**UPDATE:** we've altered some of the installation logic to perform the retry logic described below automatically so you probably don't have to worry about this scenario any longer.

   One of the first steps is to update the APT repositories via `apt-get update` which every once in a while can fail. What appears to happen in those cases is that the Ubuntu GUI has already acquired the lock and is running the update on its own.  The solution is to wait a bit and then reset the environment so that provisioning can continue.  This issue will manifest in "Ansible is not installed" errors.
   
  
positive.code: === Where did `/vagrant` go?
  There is http://stackoverflow.com/questions/42074246/vagrant-error-unable-to-mount-virtualbox-shared-folders-guest-additions-vboxs[an issue with Windows 10 and VirtualBox 5.1.16] that prevents Vagrant from starting properly.  As a workaround, we've disabled sharing of folders.  Non-Windows users can edit the `vagrantfile` and re-enable the mount if desired.
  
  **UPDATE:** the issue has been resolved in VirtualBox 5.1.18.  The `/vagrant` folder is now mounted as usual.
  
  === Vagrant Asks Me Which Network Interface To Bind To
  By default, the box is configured to join the local network as a fully accessible machine. The `desktop.vm.network "public_network"` in the `vagrantfile` is the key to this.  If you have multiple networks available on your machine, running a VPN for example, Vagrant needs to know which network you want to put your Vagrant box onto and will wait until you give it guidance.

  === Different Windowing Systems
  CAUTION: currently a work in incubation.
  
  We have branches that use different window managers that may appeal to you.  Use Git to switch to appropriate branch and run `vagrant up` to try it out.
