I am trying to install cuda on my ubuntu machine. I followed instructions from https://developer.nvidia.com/cuda-downloads to install the base installer for the cuda toolkit, which installs the cuda-toolkit-12-6 package. However when I try to check the cuda compiler version with nvcc --version it says "Command 'nvcc' not found, but can be installed with: sudo apt install nvidia-cuda-toolkit"

What am I missing here and what is the difference between these packages?

My main goal is to have cuda setup on ubuntu, I think I'm close but I'm fairly new at configuring packages like this.

    This may be of interest, including section 13. The cuda-toolkit package refers to "whatever is the latest available cuda toolkit". The cuda-toolkit-12-6 package refers to "cuda toolkit 12.6, even if there is a newer version available". Commented Aug 12, 2024 at 21:36

You need to check if the CUDA toolkit binary path is included in the PATH environment variable. If you install the toolkit on default path, you can check it in /usr/local/cuda directory.

You can check if /usr/local/cuda/bin is included in the $PATH variable or not. Once you include it you can run the nvcc --version command.

To answer your question regarding difference between cuda-toolkit-12-6 package and nvidia-cuda-toolkit, the first once is from NVIDIA official website and the second one is from apt package manager mostly used by Debian based Linux distribution. It is easier to manage a package with APT like upgrading, downgrading or removing a package but there is a chance that it will not have updated version which was released by NVIDIA.

You can have multiple version of CUDA toolkit in a system if you try to install by downloading the package from official website, I'm not sure if we can do that same with the package manager.
