“Completed with errors. See log at /var/log/cuda-installer.log for details.” and no ERROR found in log file

I have installed nvidia-driver-440 on ubuntu 16.04.7 correctly. nvidia-smi looks like below:

But…when try to install cuda10.1 or cuda11 via .run file. An error was always been encountered:
Completed with errors. See log at /var/log/cuda-installer.log for details.
So I check the log file and I didn’t find any ERROR in it. What should I do:
below is my computer system details and my ubuntu information:
1. (uname -a)Linux readitec-Lenovo-Legion-R7000P2020H 4.4.252-0404252-generic #202101170841 SMP Sun Jan 17 14:14:27 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
2. (lsb_release -a):No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.7 LTS
Release: 16.04
Codename: xenial
How should I check why the cuda install process crashed? Thanks!

have you solve this problem?
