Missing GPG Key in the ubuntu1604/x86_64 machine-learning repo directory

One of the first steps of building DIGITS is to setup access to the CUDA and ML repositories. This is failing when trying to setup access to the ml repository located at:


because the key file http://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1604/x86_64/7fa2af80.pub does not exist.

Can someone please restore the key file to this directory or update the .deb package script (nvidia-machine-learning-repo-ubuntu1604_1.0.0-1_amd64.deb) to use a different one if things are being updated?

I have to repeat this request. Please add the public key file to the repo and/or update the ubuntu1604 package. Without it, the repo is pointless.
