How to remove Ubuntu 7.10 kernel after upgrade to 8/04


Hi,

I had upgraded to Ubuntu 8.04 from Ubuntu 7.10 via Upgrade-Manager. And I had a problem: How to remove the 7.10 kernle from current Ubuntu 8.04?

Um - how did you upgrade?

I just had this with an upgrade from the CD. The grub menu gives me a choise of 7.10 or 8.04 - the reason for this was that I had inadvertently configured a dual-boot (the default) and I needed to reinstall using the "guided: using whole disk" option.

So - make sure you do not have dual-boot (fdisk -l ... how many partitions?)
If you are single-booting, then there will be only one root partition. You can remove the errant kernel with synaptic.

Do you have an entry in /boot/grub/menu.lst for Ubuntu 8.04 and is it the kernel you are running (uname -a)? If so, you can run Synaptic (or the Add/Remove software app), search for kernel and choose the old kernel for deinstallation.

If you upgraded only recently, I would recommend holding off on ridding yourself of the 2.6.22 kernel. The new kernel is still undergoing some bug-fixes in Ubuntu.

That said, the package is called linux-image-2.6.22-14-generic. The last word will be different if you installed Ubuntu with an architecture other than i386. The
Code:
uname -a
command mentioned earlier will tell you if this is the case.

Thank you for all warm help.

Thanks Simon Bridge. I have dual-boot, and replaced the Ubuntu 7.10 2.6.22-14 boot item in /boot/grub/menu.lst with Ubuntu 8.04 Linux kernel 2.6.24-16, then I can run into Ubuntu 8.04.

Follow p_quarles's advice, I make a full-backup for current installed Ubuntu that includes 7.10 and 8.04 both. Then, I delete the 2.6.22-14 kernel follow reddazz's instructions.

Um ... if you dual-booted, then you still have the old root partition taking up space. If you just want the 8.04 to be the default boot option, you can set it in menu.lst without removing the 7.10 entry.

Thank for your help.

Now, I modified the menu.lst for 8.04 kernel entry and remains the old 7.10 kernel.
