Ubuntu 21.04

nvidia-smi >> Failed to initialize NVML: Driver/library version mismatch

lspci -v | grep VGA >> 1d:00.0 VGA compatible controller: NVIDIA Corporation GP106 [GeForce GTX 1060 3GB] (rev a1) (prog-if 00 [VGA controller])

I do not know how to generate logs. I need help on where/how to troubleshoot and potentially fix this.

run nvidia-bug-report.sh as root and attach the resulting file here.

Failed to initialize NVML: Driver/library version mismatch

As the message says, the kernel modules and the libraries have different versions.

Run sudo apt purge nvidia* libnvidia*.
Then sudo apt install nvidia-driver-470.

If that is not working, then show the output of: dkms status
