I am trying to install CUDA on Ubuntu 18.04, on a headless server (no graphical), following official guide, but I face errors:
# 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 sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600 wget 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 Issues at the end of the process sudo apt-get -y install cuda:

At the time of this writing you need to resolve the conflict manually:
sudo dpkg -i --force-overwrite /var/cache/apt/archives/libnvidia-compute-450_450.36.06-0ubuntu1_amd64.deb followed by:
sudo apt --fix-broken install
