We have a hosted Ubuntu VM that is running 18.04.6 LTS. The software that we need to run apparently only supports the 5.4 kernel or earlier, but we want to upgrade to 20.04 - so our options are 20.04.0 or 20.04.1. (it does not work at all with 20.04.4). I thought I could possibly upgrade using the kernel version, but it looks like the 5.4 kernel applies to both 18.04 and 20.04.

Is there a way to indicate an interim release version with the "do-release-upgrade" command?

You can use Ubuntu 20.04 with the 5.4 non-HWE kernel.

If you already upgraded to the 5.13 kernel you can easily install and use the 5.4 kernel.

Run in a terminal

sudo apt install linux-generic

This will install the 5.4 kernel.

Then boot to this kernel using grub menu and uninstall the 5.13 kernel and headers using synaptic.
