ubuntu 20.04 LTS fresh install guide

Hello!

Another cookbook entry on how to install your freshly installed 20.04 LTS system for DLC use! Namely, CUDA, drivers, Docker, and anaconda!

sudo apt install gcc

then:

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-ubuntu2004.pin
sudo mv cuda-ubuntu2004.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget https://developer.download.nvidia.com/compute/cuda/11.3.1/local_installers/cuda-repo-ubuntu2004-11-3-local_11.3.1-465.19.01-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu2004-11-3-local_11.3.1-465.19.01-1_amd64.deb
sudo apt-key add /var/cuda-repo-ubuntu2004-11-3-local/7fa2af80.pub
sudo apt-get update
sudo apt-get -y install cuda

Then:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo ubuntu-drivers autoinstall

then:

reboot

re-open terminal and check gcc version:

gcc --version

output:

gcc --version
gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

Then finish installation:

sudo apt install nvidia-cuda-toolkit gcc-9

Then check:

nvcc --version

All set! If error messages, read them carefully as they often tell you how to fix it, or what to google :D

Now you can see CUDA, DRIVER, GPU(s):

nvidia-smi

output:
