Sample Dockerfile won't build

[robotrapta]

The example Dockerfile fails to build. The line

RUN apt-get update && apt-get install -y git

gives this 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.
The command '/bin/sh -c apt-get update && apt-get install -y git' returned a non-zero code: 100
ERROR: Service 'app' failed to build : Build failed

which smells like the image has apt-get configured with some old nvidia key. But upgrading to a newer pytorch base image pytorch/pytorch:1.11.0-cuda11.3-cudnn8-devel doesn't fix it.

Found a workaround [here](# ref: NVIDIA/nvidia-container-toolkit#257) which is to add this before apt-get update:

RUN rm /etc/apt/sources.list.d/cuda.list
RUN rm /etc/apt/sources.list.d/nvidia-ml.list solution
