updates

I'm using Ubuntu 9.1 server edition, I get this error during boot time after I ran sudo apt-get upgrade

when checking my kernel version, uname -r
returns 2.6.31-14-generic

but when i run dpkg -l 'linux-image*' | grep ^.i
I cannot find 2.6.31-14 (only contains 2.6.32*)

Following the solution in the thread: Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) doesn't work for me

I'm running the commands inside the Rescue mode by booting from the Ubuntu 9.1 Installation Disc

Do I need to update my kernel and run update-initramfs + update-grub again? If so, how can I update the kernel? apt-get install any linux-headers/image cannot change the uname -r value

Thanks!
