[SOLVED] Problems with kernel update to linux-lts-6.6.47-1

I carried out an update today. My init-system is OpenRC. Installed kernel is: 6.6.44-3-lts.
This update has provided a new kernel: linux-lts-6.6.47-1

I have installed all this successfully.


Now to the problem:

After the update, I ran “update-grub” and “grub-mkconfig -o /boot/grub/grub.cfg”. A problem appeared. I had never had a problem like this before.

The following message after “update-grub”:

Code: [Select]

Linux-Abbild gefunden: /boot/vmlinuz-linux-lts
Initrd-Abbild gefunden: /boot/intel-ucode.img /boot/initramfs-linux-lts.img

And after “grub-mkconfig -o /boot/grub/grub.cfg” this message appeared:

Code: [Select]

What should I do now? I have already searched the Internet for these errors and have not really found anything.

If I restart the PC, I will no longer be able to start Artix-Linux.

I have already tried to reinstall the boot loader, but after "artix-chroot" I get an error warning that the command could not be found.

I would try to install "linux" to compare if the Problem is there too.

Isn't “update-grub” just a wrapper that does “grub-mkconfig -o /boot/grub/grub.cfg” ?

So you would do one or the other. Both seems redundant?
But also you shouldn't need to run either when just updating the kernel. It's only needed when changing  the kernel type i.e. -lts, -zen etc.

My advice :
Post your /boot/grub/grub.cfg

Also as a failsafe before you try to reboot go here https://rodsbooks.com/refind/getting.html
and get the "A USB flash drive image" file. Unzip and use dd to write the .img file to a usb drive.

If grub fails, 99% of the time you'll get into your system by booting from the rEFInd  boot disk you just created far more easily than by trying to use the grub rescue console.
rEFInd auto detects your installations unlike grub which needs it's cfg file.

Why not? GRUB should still look for /boot/vmlinuz-linux-lts, it's not necessary to re-run grub-install or grub-mkconfig after updates - unless a different kernel has been installed.
I have already tried to reinstall the boot loader, but after "artix-chroot" I get an error warning that the command could not be found.
Was glibc or bash among the updates? Anyway, worst (unlikely) case is a boot failure, which can be cured with a live Artix ISO. You seem to know about chroot and such, so go ahead!

Yes, I had that idea too. Maybe I will test it out. But does the problem then only seem to be with linux-lts?

I used to run “grub-mkconfig -o /boot/grub/grub.cfg” after kernel updates. But once after a grub update my system stopped working because I didn't run update-grub. Since then I always run both things. It has always worked well so far.

Okay, thanks for the tip with refind. I will download it.

Well, I don't really have much experience with chroot. I used it back when I installed the system and back when my bootloader was shot. I followed the instructions and was able to rescue my bootloader.

But now it no longer works.

I have now changed the kernel and installed linux-6.10.6.artix1-1.

After executing the command, I got the same error as with linux-lts:

I am desperate, annoyed and stressed with these errors.

So after going back and forth several times. typing in several commands that did nothing, I decided to simply restart the system. I was simply fed up. And what happened, grub recognized artix on boot.

It probably loaded the necessary firmware during the boot process and everything worked. Now I'm running the new linux-lts-kernel 6.6.47-1-lts.

I have wasted a whole day looking for a problem. Simply for nothing.

If the problem had been unsolvable, I would have tried other steps. If that hadn't worked, then I was already in the process of installing a completely new Linux system.

Nothing wrong with being a bit cautious when you suspect an issue with a grub update.
And you may have learnt some new things along the way ?
That's looking on the bright side ;)

Well, didn't we tell you so? GRUB doesn't break just because the kernel got updated (unlike LILO).

Since the kernel was among the updates, grub-mkconfig couldn't load the newer module. Please, mark this thread as solved.

Yes, I have actually learned new things and refreshed old ones.  ;)

I agree.
