Created attachment 6851 [details] Patch to correct provisioning step in Vagrantfile If you follow the steps in the manual to launch vagrant (download VagrantFile, run vagrant up) then the resulting VirtualBox VM hangs during the provisioning because the grub-pc update is asking a question but there is no interactive context in which the user can answer it. The solution is to run the apt-get update with not only -y but also some magic options that make sure it really doesn't ask any questions. The issue is described here: http://askubuntu.com/questions/146921/how-do-i-apt-get-y-dist-upgrade-without-a-grub-config-prompt I attach a patch that makes it so.
