Hi all,

As just the latest chapter of some of my recent distribution-hopping adventures, I find myself needing to investigate the use of Ubuntu (or to be specific Kubuntu) LTS version. It's mainly because of third-party support, stuff that I want to use is officially supported on Ubuntu LTS, RHEL and clones (ie, Rocky) and little else. What I want is community-supported on Fedora, CatchyOS and elsewhere, but that means going through hoops and update-breakage risks that I'd care to avoid.

Here's the problem: my newish hardware isn't fully supported by kernels older than 6.16.9 and *ubuntu 24.04.3 LTS ships with 6.8. There are two ways to get newer kernels with Ubuntu LTS. One, "Hardware Enablement" (HWE) goes up to 6,14, closer but not quite. Another path, the "Mainline kernel PPA" offers kernels as current as 6.18-rc7 but is unsupported and not recommended for anything but experimental systems.

My main problem should alleviate on February 12 when Ubuntu 24.04.4 LTS is scheduled for release, with the HWE kernel will be at oldest 6.17. Between now and then I must choose between (a) hardware that isn't fully functional, (b) a provided-but-unsupported kernel update that is not recommended for anything but testing.

My question here is whether anyone reading this has any experience with Ubuntu LTS using Mainline kernels. If so, how stable was it?

Thanks!
