Step-by-step – CUDA 10 Installation in Ubuntu 20.04 Guide

Installing

2. 2. Pre-Installation Testing

   Then Verify on CUDA Capable GPU.

   lspci | grep -i nvidia

   But if you do Not see any NVIDIA hardware on Output then first install:

   sudo update-pciids

   Then try Again…

3. 3. Installing Kernel Headers

   Next Install Ubuntu’s Kernel Headers.

   sudo apt install linux-headers-$(uname -r)

   If Got “User is Not in Sudoers file” then see: How to Enable sudo.

4. 4. Setting Up CUDA Repo

   See How Setup CUDA 10 Repository for Ubuntu 20.04

   CUDA Repository Setup

   CUDA Repo for Ubuntu 20.04

5. 5. Installing CUDA 10

   Finally, Install CUDA 10 Toolkit in Ubuntu 20.04
   To search for the Available releases:

   sudo apt search cuda | grep 10

   Then for instance, to Install CUDA 10.1:

   sudo apt install cuda-10-1

6. 6. Setting Up Path

   Again Setup PATH Env Variable.
   This is necessary to Find the Binaries on System:

   echo 'export PATH=/usr/local/cuda-10.0/bin${PATH:+:${PATH}}' >> $HOME/.bashrc

   Possibly Amend the 10.0 with the Actual Version…
   And Reload Configuration simply with:

   bash
