Ruby error message starting vagrant - ruby

Question

I used to start my local VM gc-gw0 with vagrant:
vagrant up gc-gw0
but since today I get this error instead:

The strange thing is, I still started it like this yesterday without problem.
I searched a lot for this error but no hints yet. What does this error message mean? Which is the main error in the whole message?
I use
$ vagrant -v
Vagrant 1.6.5
$ ruby -v
ruby 2.1.2p95 (2014-05-08) [i386-linux-gnu]
Vagrantfile and bootstrap-testnode.sh files are here: rubo77/freifunk-gluon-example-node
But I deleted all my vms in virtualbox but still I get this error anytime I want to do anything with vagrant. seems vagrant has some problem itself. So I guess the scripts I tried have nothing to do with this error.
line 202 in /usr/lib/ruby/2.1.0/rubygems/version.rb is this:
def initialize version
raise ArgumentError, "Malformed version number string #{version}" unless
self.class.correct?(version)
#version = version.to_s.strip.gsub("-",".pre.")
#segments = nil
end
So it seems like ruby is checking a .git folder instead of a version number folder

Answer 1

I found out:
I had created a .git repository inside
~/.vagrant.d/boxes/box-cutter-VAGRANTSLASH-debian77-i386
So vagrant tried to read that folder where there should be only folders named by numbers.
I removed that .git folder and it worked

Answer 2

I got an similar vagrant misconfiguration.
For some reason when updating repos on specific configurations of the vagrant files, this can mess up the vagrant boxes. In my case I was upgrading vagrant and virtualbox with some other changes to the vagrantfile.
I had to go to
~/.vagrant.d/boxes/
and erase the old boxes that I had.
