Reading package lists...
E: The repository 'https://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1804/x86_64  Release' no longer has a Release file.
The command '/bin/bash -c apt-get update     && apt-get install -y libsm6 libgl1-mesa-glx libxext6 libfontconfig1 libxrender1     && rm -rf /var/lib/apt/lists/*' returned a non-zero code: 100

When I look in

cat /etc/apt/sources.list.d/nvidia-ml.list

I see:

deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64 /

and

if I try to use curl on that url, I get a 404 and :
<?xml version="1.0" encoding="iso-8859-1"?> 404 - Not Found

404 - Not Found

```

Suggestions?
