Installation of cuda 11.02 driver component on ubuntu 20.04 using downloaded "run" file failed

I downloaded the runfile (local) for ubuntu 20.04 from Nvidia Developer site as shown Nvida Local runfile

Image may be NSFW.
Clik here to view.

Then followed the instructions to run the program:

sudo sh cuda_11.3.0_465.19.01_linux.run

The installation failed: here is the error in /var/log/cuda-installer.log :

There are no further indications of what failed or instructions of what to do. What can/should be done next to move forward?
