```
export distro="ubuntu2404"
export arch="x86_64"
export version="570"
wget https://developer.download.nvidia.com/compute/cuda/repos/$distro/$arch/cuda-keyring_1.1-1_all.deb
sudo dpkg -i cuda-keyring_1.1-1_all.deb
sudo apt update
sudo apt install nvidia-driver-pinning-$version
sudo IGNORE_PREEMPT_RT_PRESENCE=1 apt install cuda-drivers nvidia-driver-$version-open
```
