Hi,

I’m running **Jetson Nano 4GB** with **JetPack 4.5.6 (Ubuntu 18.04)**, freshly flashed.  
After boot, I noticed **CUDA is not pre-installed** :

```auto
cat /usr/local/cuda/version.txt
# No such file or directory

nvcc --version
# command not found

```

I tried:

```auto
sudo apt-get install nvidia-cuda-toolkit

```

but it fails with “package not found.”

I also followed old instructions:

```auto
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/sbsa/cuda-ubuntu1804.pin
sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget https://developer.download.nvidia.com/compute/cuda/11.3.1/local_installers/cuda-repo-ubuntu1804-11-3-local_11.3.1-465.19.01-1_arm64.deb
sudo dpkg -i cuda-repo-ubuntu1804-11-3-local_11.3.1-465.19.01-1_arm64.deb
sudo apt-key add /var/cuda-repo-ubuntu1804-11-3-local/7fa2af80.pub
sudo apt-get update
sudo apt-get -y install cuda

```

but those links appear to be for **SBSA ARM servers** , not Jetson Nano’s ARMv8 (Tegra).

**Questions:**

1. In 2025, is there still an official CUDA download for Jetson Nano with JetPack 4.5.6?

2. Is there a way to get CUDA preinstalled with a specific JetPack version when reflashing Jetson Nano?

Any help or updated instructions would be appreciated — most guides I find are from 2020–2021 and the links are dead now.

Thanks!

Hi,

Please check your `/etc/apt/sources.list.d/nvidia-l4t-apt-source.list`

The apt will fetch corresponding jetpack version.

Thanks

Because of this command I ran out of space and I got stuck in a loop of dependencies

Hi,

Please provide your error log when run `apt install nvidia-jetpack`.  
What free space do you have before install nvidia-jetpack?

Thanks

I just cleared some space and retried the commands again.

```auto
sudo apt install nvidia-jetpack

```

It worked but however nvcc –version didnt work  
So I used this

> If you used the [Nano SD card image](https://developer.nvidia.com/jetson-nano-sd-card-image), then yes, it already has the CUDA Toolkit installed. Check under /usr/local/cuda to verify that it’s there. Check that your ~/.bashrc file has these lines at the end, and if not, add them and restart your terminal: $ export PATH=/usr/local/cuda/bin${PATH:+:${PATH}} $ export LD\_LIBRARY\_PATH=/usr/local/cuda/lib64\ ${LD\_LIBRARY\_PATH:+:${LD\_LIBRARY\_PATH}}

and it worked
