Error message: "kernel package linux-headers-5.11.0-25-generic is not supported" when installing nvidia-340 driver on 2008 MacBook Pro using fresh install of Ubuntu 20.04.2

nvidia-340 package fails to install. I need to install it in order to enable sleep function to work on my laptop.

This is a fresh Ubuntu install with everything else working fine. No problems installing other packages, only nvidia-340. I have previously been able to install nvidia-340 with no issues on this same laptop, for same Ubuntu version 20.04.2, on 26 July 2021, as well as on same laptop with a previous Ubuntu (Precise Pangolin). I installed Ubuntu 20.04.2 yesterday (9 Aug 2021) using the same Ubuntu 20.04.2 live DVD that I used before (approx. 7 July 2021).
