Nvidia drivers install error building kernel modules

I am trying to install nvidia-450 drivers via nvidia-installer on Ubuntu 20.04 for gtx1650. However install fails with:
ERROR: An error occurred while performing the step: "Building kernel modules". See /var/log/nvidia-installer.log for details.
Here is /var/log/nvidia-installer.log: https://pastebin.com/sxxcHZKK
Any help is appreciated.
