box file is 404 in Vagrant cloud

[rk295]

Hi, when running vagrant up the following error is thrown:

sensu-server: Downloading: https://vagrantcloud.com/ubuntu/boxes/trusty64/versions/1/providers/virtualbox.box
An error occurred while downloading the remote file. The error
message, if any, is reproduced below. Please fix this error and try
again.

The requested URL returned error: 404 Not Found

Changing the server.vm.box line as shown below and removing the *.vm.box_url lines fixes it.

server.vm.box = "ubuntu/trusty64"

And the same for the client.vm.box line.

Tested in Vagrant 1.6.5 on osX.
