Have you followed the guide to install cuda toolkit? Quickstart Guide — DeepStream 6.1.1 Release documentation A apt-repository will be added in this part.

I didn’t. I followed this Installation Guide Linux :: CUDA Toolkit Documentation to install the CUDA toolkit using a runfile.

It seems the ucda apt-repository is not set properly, please follow the installation guide to re-install: Quickstart Guide — DeepStream 6.1.1 Release documentation

That solves the issue. Thanks.

How to solve it?

If you’re installing DeepStream then install CUDA by following the steps documented in Quickstart Guide — DeepStream 6.1.1 Release documentation; not Installation Guide Linux :: CUDA Toolkit Documentation but follow the post-installation steps as in the latter documentation. @user57399
