What's the proper way to downgrade the kernel to 6.12 in Ubuntu 24?

Support and Help

Ubuntu Version:
Ubuntu 24.04.3 LTS

Desktop Environment (if applicable):
GNOME

Problem Description:
I’m trying to use a USB Bluetooth receiver and it’s not working. When I contacted tech support, they told me their hardware works only with LTS releases of the Linux kernel. Though I’m running an LTS release of Ubuntu, my kernel version (6.14) is possibly too new. What’s the correct way to downgrade my kernel to 6.12 LTS?

Relevant System Information:
Lenovo ThinkCentre
StarTech USB Bluetooth 5.0 Adapter

Please don’t do that :slight_smile: File an Ubuntu bug instead:
