Hi @1965281904,
I guess you are checking cuda installer logs, you need to see the driver installer logs.


Hi @ AakankshaS
the nvidia-installer.log info as follows:
nvidia-installer log file ‘/var/log/nvidia-installer.log’
creation time: Sun Aug 23 20:52:31 2020
installer version: 440.33.01

PATH: /sbin:/bin:/usr/sbin:/usr/bin

nvidia-installer command line:

Using built-in stream user interface
→ Detected 32 CPUs online; setting concurrency level to 32.
ERROR: An NVIDIA kernel module ‘nvidia’ appears to already be loaded in your kernel. This may be because it is in use (for example, by an X server, a CUDA program, or the NVIDIA Persistence Daemon), but this may also happen if your kernel was configured without support for module unloading. Please be sure to exit any programs that may be using the GPU(s) before attempting to upgrade your driver. If no GPU-based programs are running, you know that your kernel supports module unloading, and you still receive this message, then an error may have occured that has corrupted an NVIDIA kernel module’s usage count, for which the simplest remedy is to reboot your computer.
ERROR: Installation has failed. Please see the file ‘/var/log/nvidia-installer.log’ for details. You may find suggestions on fixing installation problems in the README available on the Linux driver download page at www.nvidia.com.
