Is there a stable KDE Neon?

[cookiemuncher]

For now I am booting from the Ubuntu Budgie grub menu as that detected the Neon installation and that is usable.

Could this have something to do with it (when using apt to update)?

W: file:/var/lib/preinstalled-pool/dists/jammy/Release.gpg: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

No.
The answer to your question is literally in the output: "see the DEPRECATION section in apt-key(8) for details."

In this case, the actual "issue" is that the installer left behind a config file that points to the installer media as a (temporary) source for apt which has a small number of packages (just like any *buntu installer has). It is not needed once the installation is finished.
So, remove the file /etc/apt/sources.list.d/preinstalled-pool.list and the message will go away.
But La Gatita Negra is correct, "deprecated" here means: "it is not the standard thing any longer, but still supported, so please fix it in the future"

The latest usable kernel installed is 6.5.0-25-generic. Any reason why rEFInd doesn't see it? The Ubuntu grub menu does see it.

Hi to you, too.

At present it is mostly just because of the Plasma 6 release that I am "more active"…
This will certainly become less - my other half will see to it, I'm sure.

By the way: I wonder why Kubuntu Focus is not represented a bit more in this forum (by the one or another posting) - some of the tools are quite good, and the concept is too IMHO!

Thanks for the pleasant response and the encouragement. Hopefully you will see more of me and others soon as we are pretty involved with 24.04 development. We should have some neat new tools then too!

the problem is not with KDE or Neon specifically it's because the budgie (Ubuntu 24.04) install modified the grub settings and you are no longer using Neon's grub but Ubuntu's
So to fix that as oshunluvr has said you need to reinstall Neon's Grub. and do an sudo update-grub command in the terminal. If you don't want to bother with that go to ubuntu and try the same command and Ubuntu's grub will control boot. Your Choice.

I then reboot the PC and under cmos boot manager (F11 on my PC) select neon, which immediately reboots and enters CMOS settings and will not give me the Neon grub menu.
I hope I have not missed anything.

Yes, you missed something. You installed grub to a partition - sdc2. You cannot boot to a partition.

You need to do grub-install to the drive you are trying to boot from.

I replaced the dual boot SSD (Neon and Ubuntu) with a new SSD with only KDE Neon. Let's see how that goes.

EDIT (18 Mar):
KDE Neon dual booting with windows 11 giving me no issues at all.
