安装我使用的密钥 sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv A4B469963BF863CC

但这给出了 No data 错误。gpg: keyserver receive failed: No data

我可以运行sudo apt-get upgrade，但不能更新。任何帮助，将不胜感激

即使安装了cuda，但仍然找不到cuda库，这可能是由于更新造成的。

以下对我有用

apt-key del 7fa2af80
rm /etc/apt/sources.list.d/cuda.list
rm /etc/apt/sources.list.d/nvidia-ml.list
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-keyring_1.0-1_all.deb
dpkg -i cuda-keyring_1.0-1_all.deb

我在 docker 容器中运行了这些命令，因此在 VM 中您可能需要添加 sudo。
