How to Boot Previous Linux Kernel

[Simpleton]

Hi. I don’t think I’m experiencing a “kernel panic at boot” because my mini pc starts up fine and I can do everything except update my software successfully. But I do think I need to launch my Zorin OS 18.1 Core OS with the previous Linux 6.17 kernel from the boot menu based on what is happening with the current Linux 7.0.0-28-generic kernel...

When I click “Software Updater,” I see the “Updated software is available” screen but with no details other than “88.6 MB will be downloaded.” Whenever I click “Install Now” a short bit of “updating snaps” happens but I end up at the very same “Updated software is available” screen where I started...

Anyway, I got to what-I-think-is the boot menu when, as I powered up, I hit F7 and selected “Enter Setup.” Nowhere did I see a Zorin OS option with version “6.17” of the Linux kernel. (Hitting “Esc” multiple times took me to the “grub>” command line & holding the left “Shift” didn’t do anything.)

On the “Aptio Setup – AMI” screen I have these options: Main, Advanced, Chipset, Security, Boot, Save & Exit. Under “Advanced” there is: Connectivity Configuration, CPU Configuration, Power & Performance, PCH-FW Configuration, Thermal Configuration, etc.

This is already WAY above my technical know-how especially as a Linux newbie. What is the simplest way I can get my Software Updater to work again?

In case it helps, my mini pc details: Intel N150 x 4 processor, 16 GiB memory, 256.1 GB disk capacity

Open a terminal and type

sudo apt update && sudo apt upgrade

see if that fixes the trouble

as pertaining to geting to another kernel most computers at complety off you power it on and hit either esc key or tab and a screen like this will popup

mine has a speical background...but then arrow down or use mouse to hit advanced options then choose another kernel by clicking on one you want

I am crosslinking this thread so you can see that this is not a dire experience or anything:

Software Updater continuously re-prompts for 87.4mb update

After running your command line, I saw the firefox download msg. The prompt for the 87.4MB update appeared again and I said yes. I then rebooted and ran you command again. This time the firefox msg was missing. I imagine the issue is resolved. I'll post again if the 87.4 reappears. Thanks for your support. I appreciate it. Just to be complete, I will post the output when I ran your line again. jim@Jims-Ryzen-Desktop:~$ sudo apt update && sudo apt upgrade [sudo] password for jim: Hit:1 Index…

It is not the kernel at fault, nor a system failure of any kind. Just a bleeping computer annoyance.

Mostly, it seems related to Snap packages. They get stuck in the pipe.
You can jiggle the handle using terminal

sudo snap refresh

If it is a flatpak update doing it (They do this, too):

flatpak update

In addition to @wesoliv429's suggestion to run sudo apt update && sudo apt upgrade

@Aravisian Thanks

[Simpleton]

Thank you for the fix! Typing that command was like waving a magic wand. = )

As for my mini's setup, I guess it's not like most computers. I'm just happy when everything works.

I appreciate your reply as well. Thank you for the crosslink & explanation.
