Using latest vagrant version throws an exception

[morazow]

Running the vagrant up throws the following exception:

It is related to this issue: mitchellh/vagrant-aws#566

I solved the issue using the workaround suggested on this comment: mitchellh/vagrant-aws#566 (comment)

I think vagrant-aws seems to be not very actively maintained, general solution would be to use differnt aws vagrant plugin.

I can re-create this error and also can confirm that adding the workaround you pointed to resolves the issue:

diff --git a/aws/Vagrantfile b/aws/Vagrantfile

 Vagrant.configure("2") do |config|

Once I got all cleaned up, I will create a new PR for the AWS fixes.
