Quick help with Kernel update

[pred2k]

Hi, i want to update my Kernel (because the new vulnerability) on my rented dedicated server which is running with Ubuntu 8.10.

Current Kernel is a standard 2.6.24-23-generic

With apt-get upgrade i saw him downloading 2.6.27-14-generic

I'm not sure what to do, to use the new kernel. I already updated a kernel on my home-server with ubuntu, but i dont want to make mistakes at the update (because is a server from the hoster server4you.de).

after
apt-get upgrade i did
update-grub and got this message here:


A new version of /boot/grub/menu.lst is available, but the version installed currently has been locally modified.
What would you like to do about menu.lst?
"Line by line differences between versions" shows this:

Can i choose "install the package maintainer's version" ?

I'm a little confused, when i login to the shell i always get this message:

Dear customer,

Important information regarding kernel-updates:

If you want to use your own kernel, please make sure you don't touch the
kernel boot parameters (append) as some of our hardware requires the
parameters acpi=ht and/or noapic.

in this lines:

-kernel /vmlinuz-2.6.24-23-generic root=UUID=98c9b88d-2c73-4add-b588-53ac3308cb4f ro vga=ext
+kernel /vmlinuz-2.6.27-14-generic root=UUID=98c9b88d-2c73-4add-b588-53ac3308cb4f ro acpi=ht vga=ext

before there where just "ro vga=ext" as argument for the kernel.
Now "acpi=ht" was added.

The message from the hirer, says "acpi=ht" is required. But it wasn't configured before.

What other step do i have to do after update-grub?

i choosed "install the package maintainer's version" and rebooted.
Everything is fine now.
Just where a little confused.
