We've found a workaround, commenting out this block does the trick:

config.vm.provision :lsb_check do |lsb|

lsb.version = '14.04'

end

In addition to adding:

require 'mediawiki-vagrant/environment'

Before MediaWikiVagrant::Environment.new

Gilles reported on irc that he has Vagrant 1.4.3 installed. This may be part of the problem. I wonder if we should start checking for a minimum Vagrant version and/or testing plugin changes in a wider variety of Vagrant versions ourselves.

Updating vagrant to the latest stable fixed it

I would guess that the older Vagrant ships with a ruby version that doesn't like something our plugin is doing. Maybe use of require_relative?

1.4.3 is the current version in Debian and Ubuntu apt repos. Our documentation says "Get the latest Vagrant (the version must be 1.2.6 or higher; For NFS, use 1.5.4 and up)". So we should either update the docs to say 1.6.0+ and check somehow in the Vagrantfile or fix things to work back to at least 1.4.3.

Repro'd this on OS X by specifying "v1.4.3" in the Gemfile and running bundle exec vagrant config --required.

Gemfile:

gem 'vagrant', git: 'https://github.com/mitchellh/vagrant.git', tag: 'v1.4.3'

Looks like Vagrant 1.4 doesn't support options for commands—despite the fact the plugin API interface is supposed to be the same. :/
