According to the NVIDIA Technical Blog, on Ubuntu we can install the drivers by

sudo apt-get install nvidia-open

However, as of April 2026 and Ubuntu 26.04, this returns “Error: Unable to locate package nvidia-open” on ThinkPad P16 Gen 3, which has NVIDIA RTX Pro 5000 Blackwell GPU.

I tried also

$ sudo apt-get install -V nvidia-kernel-source-open
 
$ sudo apt-get install nvidia-open

The error is similar. Did I miss something? Thanks.

Did you add the 2604 cuda repo?

Thank you. So this is what I missed. Could you remind me where in the NVIDIA Technical Blog I can find the instructions for adding this repo?
