12.04 upgrade kernel version seems wrong

[Ron Jones]

I'f finished the upgrade to 12.04, and all seems to be working well.

However, when I reboot (after running update-grub) the java test at http://java.com/en/download/testjava.jsp tells me I'm running kernel 3.0.0-16-generic.

I thought 12.04 upgraded to 3.2?

Hi

Open a terminal and type


uname -r

You'll be looking for kernel


3.2.0-23-generic

Kind regards

well, now I've gone and made a mess... I used synaptic to remove the 3.0.0 kernel image (because 3.2was installed in the upgrade), and ran grub-update.

upon reboot, I got the "cant find boot image" error. What's the best way to reconnect grub with the kernel image you want it to use?

Not an answer to you last problem (removing the kernel, do you really think that helps?!) but I had the same problem and after simply waiting half an hour (and looking at the new system) I was presented with an upgrade to the last version. My kernel is now 3.2.0-24-generic according to the java test.

Boot into a live CD/USB and update grub.

That is what i would try first.

You can chroot into the install.

Did you have any special setup such as RAID or LVM ?

Kind regards

hmmm.... Yep, I'm downloading an install disc now...and, YES, I have software RAID configured on my install. My assumption is that I'll need to take special steps to keep it. Though I was really hoping that by downloading the 12.04-alternate-amd64.iso, it would automatically recognize the RAID setup on the discs and ask If i want to keep it.

I don't suppose there's a way to enter into the grub command line at the boot screen (which still shows 3.0.0-16-generic as a boot option, though selecting it still results in "error: file not found" & "error: you need to load the kernel first"), and probe for the correct image is there?

I got the issue resolved (got the machine booted up) by following the instructions here:
http://ubuntuforums.org/showthread.php?t=1195275

set root
linux /boot/vmlinux... root=
initrd /boot/initrd.img...
boot.

So, it looks as if this can be marked as "resolved." I'll start another thread for the remaining issue.
