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 :
cat /usr/local/cuda/version.txt
# No such file or directory
nvcc --version
# command not found
I tried:
sudo apt-get install nvidia-cuda-toolkit
but it fails with “package not found.”
I also followed old instructions:
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:
In 2025, is there still an official CUDA download for Jetson Nano with JetPack 4.5.6?
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 try below commands
sudo apt update
sudo apt install nvidia-jetpack
Thanks
Doesnt this install latest Jetpack v6? How will this command help actually? @DavidDDD
Hi,
Please check your /etc/apt/sources.list.d/nvidia-l4t-apt-source.list
The apt will fetch corresponding jetpack version.
Thanks
Hi,
Please try mentioned commands.
It will fetch JP 4.6.5 package.
Thanks
Because of this command I ran out of space and I got stuck in a loop of dependencies
Output:
nano@nano-desktop:~$ cat /etc/apt/sources.list.d/nvidia-l4t-apt-source.list

Hi,
Please provide your error log when run apt install nvidia-jetpack
.
What free space do you have before install nvidia-jetpack?
Thanks
I am skipping this method and trying to reflash from SDK manager. Now it has whole another error.
I just cleared some space and retried the commands again.
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 , 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
