Magento U Virtual Machine - Warning: Authentication failure. Retrying

Question

I just tried to 'vagrant up' the VM from Magento U, and was surprised to get this as a response:

  Bringing machine 'default' up with 'virtualbox' provider...
    ==> default: Clearing any previously set forwarded ports...
    ==> default: Clearing any previously set network interfaces...

This worked fine before, but with VirtualBox 5.0 and Vagrant 1.7.4, suddenly no dice. How can I make this work?

Answer 1

I tried a ton of things to fix this, but getting Vagrant to create a new key was the way to go.

1. Boot the machine with the GUI enabled. Add this to your Vagrantfile:

   config.vm.provider :virtualbox do |vb|

   vb.gui = true

2. Log into your virtual machine from the GUI, and run these commands :

   mkdir -p /home/vagrant/.ssh

   wget --no-check-certificate https://raw.github.com/mitchellh/vagrant/master/keys/vagrant.pub -O /home/vagrant/.ssh/authorized_keys

   chmod 0700 /home/vagrant/.ssh

   chmod 0600 /home/vagrant/.ssh/authorized_keys

   chown -R vagrant /home/vagrant/.ssh

Vagrant will generate a new key, and you should be good to go.
