I upgrade my kernel

when I run update-grub, these are found

Searching for splash image ... none found, skipping ...
Found kernel: /boot/vmlinuz-3.4.0-3-generic
Found kernel: /boot/vmlinuz-3.2.0-24-generic-pae
Found kernel: /boot/vmlinuz-3.2.0-24-generic
Found kernel: /boot/vmlinuz-3.0.0-20-generic
Found GRUB 2: /boot/grub/core.img
Found kernel: /boot/memtest86+.bin
Updating /boot/grub/menu.lst ... done

but when run uname -r, the kernel is 3.0.0-20.

How can I solve that?

You have tagged your question with grub2 but GRUB is updating menu.lst. Are you still using GRUB 1? What is the version number shown on your GRUB boot menu? screenshot – irrational John Jun 4 '12 at 6:17
I retagged, it appears this may be an installation upgraded more than once, with the original install using grub1? Because grub2 is also installed (see line 6). – izx Jun 4 '12 at 7:49

When you upgrade the kernel, you must usually reboot to switch to the new kernel.

I had the same issue. What worked for me was to install GRUB2 because I was using grub 0.97. after you install grub2, update-grub and reboot the new kernel will be listed in the boot menu.
