Installing nvidia-cuda-toolkit

Hello,

I just freshly installed the Nvidia drivers and CUDA on my Linux computer. After adding the required keyrings,

sudo apt autoremove nvidia* --purge
sudo apt install nvidia-driver-535-server
sudo apt install cuda

After rebooting, nvidia-smi returns the following

Since I want to use nvcc, I tried installing it with sudo apt install nvidia-cuda-toolkit. But this returns the following

What am I doing wrong :'). Any help will be very much appreciated

I have fixed it with

conda install -c "nvidia/label/cuda-11.7.0" cuda-toolkit

Cheers
