I’ve faced the same error when installing CUDA 12.3+cuDNN 8.9 on Ubuntu/WSL (in Windows 11) with following this guide.

For me the issue was that the cudnn9-cuda-12 package name mentioned in the tutorial by default didn’t match the one I had locally.

I’ve found the correct one by running:

apt-cache search cudnn

The correct one was libcudnn8 in my case (but I’ve also installed the *-dev and *-samples ones as well just in case).
