Problem Description:
System updated to 6.8.0-94 a day or two ago, and then today updated Gnome, which required a reboot. upon rebooting the system stopped, reporting that the kernel could not be found.
Even though 6.8.0.94 was listed, selecting it took me straight back to the same initial error screen. It was only after selecting the previous version, 6.8.0-90, was I able to get my system to boot up.
When Software Updater upgraded the system to 6.8.0-94, there were no errors reported.
After Software Updater brought in Linux 6.8.0-94 did you reboot? We are usually informed by Software Updater to reboot when a new Linux kernel is installed.
I am trying to identify if the kernel is broken or if the upgrades to Gnome messed things up.
Please load into kernel Linux 6.8.0-90 and run in a terminal the command sudo update-grub
Watch the printout. Do you see Linux 6.8.0-94 listed?
My advice would be to continue loading Linux 6.8.0-90 and do regular updates through the terminal. You may get replacement kernel or replacement packages to the Gnome packages that are messing things up. If that is what they are doing.
I advise not to use Software Updater at present as it removes older kernels when it installs a new kernel. That will remove the Linux 6.8.0-90 kernel. Which you do not want to happen until you are sure that you have two working kernels available.
Why do you say you are using Ubuntu 24.04 LTS? I am on Ubuntu 24.04.03 LTS and it has Linux 6.14.0-37 generic kernel. Ubuntu 22.04.5 LTS has the 6.8 kernel series. Ubuntu 22.04 LTS is in support life until April 2027.
Below is the output in Terminal, from running that command:
31 packages can be upgraded. Run āapt list --upgradableā to see them.

System hasnāt asked to reboot after a full Kernel & associated files for quite some time actually, and I usually have to run Software Updater again to remove the package (something it was doing automatically for a while).
6.8.0-94 is definitely there, even checked the core system files with āFilesā.
I originally had a Nvidia graphics card, which subsequently died, and I replaced with a Radeon one.
Not sure what was going on last night, had around 2Gb of updates appear in Software Updater, and in all the upgrades it re-installed 6.8.0-94, and on reboot, it all loaded up fine.
