    You say 20.04.3, but kernel 6.5? If using newer 22.04.3 kernel should be 6.5 but with 22.04.3 you also have newer drivers? How new is system, what brand/model? Have you updated firmware for UEFI and if SSD its firmware?

    If you're using 20.04.3 you're years behind on applying security fixes (fridge.ubuntu.com/2022/02/25/ubuntu-20-04-4-lts-released shows the ISO release date, but installed systems upgraded before that date, so you've not applied upgrades for two years??) but 6.5 kernel implies as @oldfred said that your details are incorrect and you're not using the Ubuntu 2020-April release. If you're using 20.04.3 as stated; your system is using revoked keys & thus secure-boot won't be possible until you upgrade to newer keys... but I doubt you're using 20.04 as you state.

  • You can confirm your version using command: lsb_release -a

Known Issue

There is a bug report on this issue:

No serious consequences reported

However, according to a comment on the link, ii appears the message doesn't effect operation:

I should note that this warning is harmless. It’s due to the wrong size being declared on some arrays in UVM. You can see it in the code here: https://github.com/NVIDIA/open-gpu-kernel-modules/blob/main/kernel-open/nvidia-uvm/uvm_pmm_gpu.c#L224 135

These are C “flexible array members” and should just be declared with no size.
