Prior to 8.0, kernel updates were delivered through the lite-updates mechanism.

On a version 8.0 system, the Linux Lite Updates app reports the system is fully up to date.
Meanwhile, Lite Kernel Manager shows there is a potential kernel update from 7.1.0 to 7.2.0.

Should a user be manually checking Lite Kernel Manager or have I missed something?

That's deliberate. Upgrading custom kernels should only be done if you have new hardware that requires it.

Thank you. I may be over thinking things but I assume there is a relationship between the ubuntu 26.04 kernel and the Lite custom kernel.  The base ubuntu kernel gets changes, but the Lite custom Kernel seems to be static.

If the base Ubuntu 26.04 were to be patched for a kernel security vulnerability, a new kernel may be released.  Prior to version 8 new kernels were routinely delivered through the update mechanism with a reboot.

Would this theoretical patch to the ubuntu kernel feed into the Lite custom kernel or would the ubuntu kernel patch be delivered by other means ?

Thanks again.

Take a look at the Kernel pages from the main website for all the information.

We've actually switched from the Ubuntu base kernel to the raw kernel from Linus and friends 🐧

Thanks for pointing this out!
On my system, the recommended update is to 7.2.
I've been testing many kernels over the years, mostly due to drivers rendering poor results.
What I've learned from this, is that a manual update is the most reliable path.
Changing the boot sequence in GRUB, in not such a catastrophic task, so in case of some trouble one can move back and forth according to the testing results, than make the best kernel the default boot option.
Another thing is the one Jerry pointed out: Any trouble? Try another kernel; else, stick with the current.
It so happens I have some trouble with my wife's laptop (See the AMD Radeon 780M posts).
While now it seems that the driver problem got solved (or mostly, can't be sure yet), a kernel upgrade might lead to better results.
Now having the LKM + Lite GPUDB, we can go further exploring the performance and having those tested and compared with similar data (CPU, GPU, RAM, kernel, vendor)
My approach on that, is slightly different.
Instead of testing on my daily configuration, I use a second media (SSD) and the Delock 47230 unit so I can easily switch from one drive to the other. Having in fact the same machine but a slightly different setup, allows me to avoid unnecessary risks in case of failure.
Having backups for all partitions (and the same partitioning scheme), reduces very much the risks I need to assume. I know this goes only for a desktop setup, but I guess that if one needs to do heavy testing, a similar solution can be figured out even for laptops.
There is one that means installing on a SATA (or M.2) and working from the external media, via UEFI "Boot Options".
I did it several times, so it works.
Getting back to the question, if Jerry decides to update some Lite Kernel from the available custom ones, I guess switching from the installed one to Lite kernel is not such a difficult task.
My only experience regarding replacing the standard kernel, is related to using a low latency kernel and it got updated. But unfortunately, this was true until LL 8.0 came out. Now, I have to do the testing and this might take some time.

Best regards!
