```bash
# get md5sums
wget https://developer.download.nvidia.com/compute/cuda/12.4.1/docs/sidebar/md5sum.txt
#
# setup cuda apt repo
wget https://developer.download.nvidia.com/compute/cuda/repos/wsl-ubuntu/x86_64/cuda-wsl-ubuntu.pin
sudo mv cuda-wsl-ubuntu.pin /etc/apt/preferences.d/cuda-repository-pin-600
#
# download installer and check md5sum
wget https://developer.download.nvidia.com/compute/cuda/12.4.1/local_installers/cuda-repo-wsl-ubuntu-12-4-local_12.4.1-1_amd64.deb
md5sum --check --ignore-missing md5sum.txt
#
# try to install cuda (this will fail, but it puts the keyring file in the correct spot)
sudo dpkg -i cuda-repo-wsl-ubuntu-12-4-local_12.4.1-1_amd64.deb
#
# copy cuda gpg keyring to keyrings 
sudo cp /var/cuda-repo-wsl-ubuntu-12-4-local/cuda-*-keyring.gpg /usr/share/keyrings/
#
# install cuda (this time for real)
sudo dpkg -i cuda-repo-wsl-ubuntu-12-4-local_12.4.1-1_amd64.deb
#
# install cuda-toolkit
sudo apt update
sudo apt install cuda-toolkit-12-4
#
# setup path
# sudo apt install plocate
locate nvcc
# -> returns /usr/local/cuda-12.4
# add these lines to your .profile (.zshrc, ...)
#
# export PATH="/usr/local/cuda-12.4/bin:$PATH"
# export LD_LIBRARY_PATH="/usr/local/cuda-12.4/lib64:$LD_LIBRARY_PATH"
#
# after source-ing, check version of nvcc
nvcc -V
```

## check cuda installation with cuda samples

```bash
git clone https://github.com/NVIDIA/cuda-samples
cd cuda-samples/Samples/1_Utilities/deviceQuery
make
./devicequery
```


### if the cuda-toolkit install fails with unmet dependencies

>https://askubuntu.com/a/1493087 (jspinella, 2023, CC BY-SA 4.0)

1. Open the *new* file for storing the sources list

    ```bash
    sudo nano /etc/apt/sources.list.d/ubuntu.sources
    ```

2. Paste in the following at the end of the file: 

    ```raw
    Types: deb
    URIs: http://archive.ubuntu.com/ubuntu/
    Suites: lunar
    Components: universe
    Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
    ```

3. Save the file and run `sudo apt update` - now the install command for CUDA should work.
