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:
http://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1604/x86_64/
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?
