I can’t use nvidia-smi $ nvidia-smi NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running. tried: $ sudo apt-get install -f nvidia-384 libcuda1-384 nvidia-opencl-icd-384 Reading package lists… Done Building dependency tree Reading state information… Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: ``` The following packages have unmet dependencies: libcuda1-384 : Depends: nvidia-headless-390 but it is not going to be installed nvidia-384 : Depends: nvidia-driver-390 but it is not going to be installed nvidia-opencl-icd-384 : Depends: nvidia-headless-390 but it is not going to be installed E: Unable to correct problems, you have held broken packages. ``` ---

Please run the following command and upload the file named `nvidia-smi-troubleshooting.txt` that the command produces: ```auto sudo apt update &> nvidia-smi-troubleshooting.txt ``` The command will show if you have the latest packages from your configured apt repositories. ---

The `http://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64` NVIDIA repo is probably what’s causing the problem. You can run `grep -r developer.download.nvidia.com /etc/apt/sources.list.d` to find the APT list that contains the NVIDIA repo. Delete the list. Run `sudo apt update &> nvidia-smi-troubleshooting.txt` again so we can see the new output. (Also, you might want to comment out line 57 of `/etc/apt/sources.list` to suppress all the `[…] is configured multiple times in /etc/apt/sources.list:57 and /etc/apt/sources.list.d/lambda-repository.list:1` warnings you’re receiving.) ---

Run `sudo apt update && sudo apt upgrade`. That should upgrade all of your packages installed from APT repositories, including Lambda Stack—and fix the problem you’re experiencing with package dependencies being unmet. ---

This was fixed by reinstalling a new recovery linux image (formatting the workstation)
