今天在linux上装cuda，进行到sudo add-apt-repository “deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/ /”
时，出现报错：
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

解决办法：
运行：sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A4B469963BF863CC（这里填上面NO_PUBKEY后的那串编码）
运行后显示：
gpg: key A4B469963BF863CC: public key “cudatools cudatools@nvidia.com” imported
gpg: Total number processed: 1
gpg: imported: 1

再run：sudo add-apt-repository “deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/ /”

解决
