Error while installing berkshelf plugin

[quoidautre]

Hi,

There's an error with the berkshelf plugin. I'm on Ubuntu 13.10 and Vagrant 1.5.1, and Ruby 1.9.3p194 (2012-04-20 revision 35410) [i686-linux] {gem : 1.8.23} :

$ vagrant plugin install vagrant-berkshelf
Installing the 'vagrant-berkshelf' plugin. This can take a few minutes...
The plugin(s) can't be installed due to the version conflicts below.
This means that the plugins depend on a library version that conflicts
with other plugins or Vagrant itself, creating an impossible situation
where Vagrant wouldn't be able to load the plugins.

You can fix the issue by either removing a conflicting plugin or
by contacting a plugin author to see if they can address the conflict.

Vagrant could not find compatible versions for gem "celluloid":
  In Gemfile:
    vagrant-berkshelf (>= 0) ruby depends on
      celluloid (~> 0.13.0) ruby

    vagrant (= 1.5.1) ruby depends on
      celluloid (0.15.2)

As per issue 163 of Vagrant-Berkshelf

only the pre-release version of Vagrant-Berkshelf currently works with Vagrant 1.5. You will need to install that instead.

Apparently you need to install latest verions

vagrant plugin install vagrant-berkshelf --plugin-version 2.0.0.rc2
