Step-by-step – CUDA 11 Installation in Debian Bullseye

Installing

2. 5. Installing CUDA 11

   Finally, Install CUDA 11 Toolkit in Debian Bullseye
   To search for the Available releases:

   sudo apt search cuda | grep 11

   So for instance, to install the complete CUDA 11.4 Release play:

   sudo apt install cuda-11-8

   Where for the CUDA 11.4 Driver only:

   sudo apt install cuda-toolkit-11-8

   Finally, instead to Install the available CUDA 11 from the Apt Repo:

   sudo apt install nvidia-cuda-toolkit

3. 6. Setting Up Path

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

   echo 'export PATH=/usr/local/cuda-11.8/bin${PATH:+:${PATH}}' >> $HOME/.bashrc

   Possibly Amend the 11.8 with the Actual Version…
   And Reload Configuration simply with:

   bash
