问题描述

docker 环境为 ubuntu 18.04，在 nvidia devel docker 基础上构建自己 docker 时，apt update 会提示 Public GPG key error 相关错误，比如：

Get:7 https://developer.download.nvidia.cn/compute/cuda/repos/ubuntu1804/x86_64  InRelease [1581 B]
Err:7 https://developer.download.nvidia.cn/compute/cuda/repos/ubuntu1804/x86_64  InRelease                                 
  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A4B469963BF863CC
Ign:8 https://developer.download.nvidia.cn/compute/machine-learning/repos/ubuntu1804/x86_64  InRelease   
W: GPG error: https://developer.download.nvidia.cn/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.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

解决方法

在 Dockerfile 中添加以下语句：

RUN rm /etc/apt/sources.list.d/cuda.list
RUN rm /etc/apt/sources.list.d/nvidia-ml.list
RUN apt-key del 7fa2af80
RUN apt-get update && apt-get install -y --no-install-recommends wget
RUN wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-keyring_1.0-1_all.deb
RUN dpkg -i cuda-keyring_1.0-1_all.deb

注意非 ubuntu18.04 ,deb 相关地址可能需要更换，具体见网址：https://developer.download.nvidia.com/compute/cuda/repos/
