Testing on Ubuntu Trusty 64-bit, set up MediaWiki-Vagrant. Yay! Then went to set up a clean Vagrant instance to try other stuff, and found it failing:

brion@lino:~/src/vague$ vagrant init hashicorp/precise64
A Vagrantfile has been placed in this directory. You are now
ready to vagrant up your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
vagrantup.com for more information on using Vagrant.
