docker build doesn't work

If you try to build the Docker container you get an error:

Reading package lists...                                                                                                                                                                                                                    
W: GPG error: https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64  InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A4B469963BF863CC
E: The repository 'https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64  InRelease' is not signed.     

It turns out Nvidia changed the signing keys for their apt repo.

Adding the following to the Dockerfile before the RUN apt-get update line fixes it:

RUN apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/3bf863cc.pub
