Vagrant: Vagrant 2.1.4 breaks plugin detection / install script

[JohnMaguire]

Vagrant version

Vagrant 2.1.2 (downgraded) / Vagrant 2.1.4

Host operating system

Linux 4.18.5-arch1-1-ARCH

Guest operating system

N/A

Vagrantfile

# Handle installation of external plugins required for this Vagrantfile to work
required_plugins = %w(
  vagrant-s3auth
  vagrant-sshfs
)
needs_restart = false
toplevel_dir = File.dirname(File.expand_path(__FILE__))
required_plugins.each do |plugin|
  # Install any required plugins that are missing
  unless Vagrant.has_plugin? plugin
    # Plugin is not installed yet, so attempt to install it now.  Bail out on
    # failure so we don't get stuck in an infinite loop.
    # :chdir added to avoid recursively loading this file while loading plugins (https://github.com/hashicorp/vagrant/issues/9972)
    system("vagrant plugin install #{plugin} --plugin-clean-sources --plugin-source file://#{toplevel_dir}/vagrant/gems", :chdir => "/tmp") || exit!
    needs_restart = true
  end
end
if needs_restart
  # Relaunch Vagrant so the plugin is detected. Exit with the same status code.
  exec "vagrant #{ARGV.join' '}"
end

Expected behavior

VM brought up (as Vagrant 2.1.2 does)

Actual behavior

Plugin install loop:

Installing the 'vagrant-s3auth' plugin. This can take a few minutes...
Installed the plugin 'vagrant-s3auth (1.3.2)'!
Installing the 'vagrant-sshfs' plugin. This can take a few minutes...
Installed the plugin 'vagrant-sshfs (1.3.0)'!
Installing the 'vagrant-s3auth' plugin. This can take a few minutes...

I'm seeing this error which I believe to be the same issue:

-----> Creating <config-access-cub-rh7>...
       Vagrant failed to initialize at a very early stage:

       There was an error loading a Vagrantfile. The file being loaded
       and the error message are shown below. This is usually caused by
       a syntax error.

       Path: /home/jay/local/data/sis/git/cookbooks/cub_shibboleth/.kitchen/kitchen-vagrant/config-access-cub-rh7/Vagrantfile
       Line number: 20
       Message: NameError: uninitialized constant VagrantPlugins::Registration

(The file /home/jay/local/data/sis/git/cookbooks/cub_shibboleth/.kitchen/kitchen-vagrant/config-access-cub-rh7/Vagrantfile is managed by TestKitchen and was deleted soon after so unfortunately I don't have a copy to share right now, but I it referenced VagrantPlugins::Registration so that it could configure Red Hat licensing at VM creation time)

no such error on Vagrant 2.1.2, and the vagrant-registration plugin is reported as being installed:

I'm seeing the same symptoms as the original report.

There was block of code in my VagrantFile which was forcing to install plugins, somehow it looks creating problem. I commented it to out and that fixed the issue

## Install plugins from the required_plugins list
required_plugins = %w( vagrant-vbguest vagrant-hostmanager )
plugins_to_install = required_plugins.select { |plugin| not Vagrant.has_plugin? plugin }
if not plugins_to_install.empty?
  puts "Installing plugins: #{plugins_to_install.join(' ')}"
  if system "vagrant plugin install #{plugins_to_install.join(' ')}"
    exec "vagrant #{ARGV.join(' ')}"
  else
    abort "Installation of one or more plugins has failed. Aborting."
  end
end

maybe also related to https://github.com/hashicorp/vagrant/issues/10186
could be that because of the double loading of the vagrantfile some (environment) variables are not set, which maybe also could lead to this problem.
