问题形容：
当应用 Dockerfile 从蕴含 cuda 的镜像建设新的 image 的时候，显示以下 bug：
Step 7/8 : RUN apt-get update && DEBIAN_FRONTEND="noninteractive" apt-get install -y -q libcudnn6=$CUDNN_VERSION-1+cuda8.0 libcudnn6-dev=$CUDNN_VERSION-1+cuda8.0 && rm -rf /var/lib/apt/lists/*

在 Dockerfile 运行这行代码
RUN apt-get -qq -y update && \
DEBIAN_FRONTEND=noninteractive apt-get -qq -y install \
gcc \
... \之前退出以下代码
RUN rm /etc/apt/sources.list.d/cuda.list && rm /etc/apt/sources.list.d/nvidia-ml.list胜利解决！
