30秒解决nvidia-smi报错：NVIDIA-SMI has failed because it couldn‘t communicate with the NVIDIA driver

(1) Execute the following command to view the local driver

ls -l /usr/src/

The print is as follows, mine is nvidia-srv-470.129.06

drwxr-xr-x  7 root root 4096 5月  24 22:36 linux-headers-5.13.0-44-generic
drwxr-xr-x  7 root root 4096 6月   8 20:26 linux-headers-5.13.0-48-generic
drwxr-xr-x 24 root root 4096 5月  24 22:36 linux-hwe-5.13-headers-5.13.0-44
drwxr-xr-x 24 root root 4096 6月   8 20:26 linux-hwe-5.13-headers-5.13.0-48
drwxr-xr-x  9 root root 4096 5月  29 15:13 nvidia-srv-470.129.06

If there is no driver, update additional drivers. Perform the following two steps:

1. try direct download

sudo add-apt-repository ppa:graphics-drivers/ppa && sudo apt update

If the following error is reported,

: GPG error: https://developer.download.nvidia.cn/compute/cuda/repos/ubuntu2004/x86_64  InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A4B469963BF863C2

Also perform step 2, replacing your own key:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys  A4B469963BF863CC

Or execute nvidia-smi, and follow the prompts to download the driver.

(2) Use dkms to install the driver

sudo dkms install -m nvidia -v srv-470.129.06

There will be the following information:
