Can't run nix-docker in current vagrant

sudo -E nix-docker -b -t my-image samples/wordpress.nix

Running the command without sudo complains that it must be run with sudo -E.

Not sure where to go from here.

Ubuntu Raring is EOL, and should switch to Trusty.

And the sudo -E needs to have the full path to nix-docker as its not in root's path in default vagrant installation.
