Installing CUDA 11.x on Jetson Nano

Hi all -

Downloaded and installed the newest Jetson Nano SD image - jetson-nano-jp45-sd-card-image.zip

Tried to update to CUDA 11.0 (same thing happens with CUDA 11.2 update) buy:

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 http://developer.download.nvidia.com/compute/cuda/11.0.2/local_installers/cuda-repo-ubuntu1804-11-0-local_11.0.2-450.51.05-1_arm64.deb
sudo dpkg -i cuda-repo-ubuntu1804-11-0-local_11.0.2-450.51.05-1_arm64.deb
sudo apt-key add /var/cuda-repo-ubuntu1804-11-0-local/7fa2af80.pub
sudo apt-get update
sudo apt-get -y install cuda

The last command gives these errors:

E: Sub-process /usr/bin/dpkg returned an error code (1)

I’m uncertain how to clean this up as aptitude database is now hosed.
Is there a way to update the Nano to an 11.X version of CUDA?

Also -
After I update CUDA, can I update the Nano to Ubuntu 20.04 from the 18.04 default in the above SD card image without encountering issues?

thanks

Hi,

Sorry that there is no CUDA 11.x support on Jetson device currently.
The limitation comes from GPU driver. Please wait for our next major JetPack update to get a compatible driver.

However, there is a sharing to run Ubuntu 20.04 with docker on Xavier.
Please check below topic for the information:

Thanks.
