我正在尝试按照官方指南在 Ubuntu 18.04 上的无头服务器（无图形）上安装 CUDA ，但我遇到错误：
# remove previous
apt-get update
apt-get remove --auto-remove nvidia-cuda-toolkit
apt-get purge nvidia-cuda-toolkit
apt-get purge --auto-remove nvidia-cuda-toolkit
apt-get autoremove
# install new
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-ubuntu1804.pin
sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget http://developer.download.nvidia.com/compute/cuda/11.0.1/local_installers/cuda-repo-ubuntu1804-11-0-local_11.0.1-450.36.06-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1804-11-0-local_11.0.1-450.36.06-1_amd64.deb
sudo apt-key add /var/cuda-repo-ubuntu1804-11-0-local/7fa2af80.pub
sudo apt-get update
sudo apt-get -y install cuda
流程结束时的问题sudo apt-get -y install cuda：
Errors were encountered while processing:
/tmp/apt-dpkg-install-7DzKEt/135-nvidia-compute-utils-450_450.36.06-0ubuntu1_amd64.deb
/tmp/apt-dpkg-install-7DzKEt/140-nvidia-utils-450_450.36.06-0ubuntu1_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
再做sudo apt-get -y install cuda …
