I just downloaded Vagrant and did the settings as well as install virtual box. I just can\'t start my project (vagrant up). I have a vagrant file and so on. What can I do?>
I just experienced this error. In my case I installed vagrant via apt-get which installed 1.7.x..
I removed 1.7.x and installed 2.0.3 directly https://www.vagrantup.com/downloads.html
