I want to install kernel source in Ubuntu 12.04 which is not installed. I have checked the same using the following command :

dpkg -s kernel

Output is Kernel is not installed no information available

Hence I have followed the following steps to install the same:

1.Installed the Dependencies by the following command:

sudo apt-get install gcc libncurses5-dev git-core kernel-package fakeroot build-essential
sudo apt-get update && sudo apt-get upgrade

1. Download kernel source by the following command:

   wget http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.5.tar.bz2
   tar -xvf linux-3.5.tar.bz2
   cd linux-3.5/
   

3.Compiled the source code to generate the .deb packages by the following command

make-kpkg clean
fakeroot make-kpkg --initrd --append-to-version=-spica kernel_image kernel_headers

1. Install the .deb packages (two .deb packages generated, one is to install the kernel headers, another one is to install the kernel image) by the following command

   sudo dpkg -i linux-*.deb
   

But after reboot it seems kernel is not installed (checked by dpkg -s kernel). Please tell where I am going wrong.

Also, In step 3, I guess I am installing a new kernel (named spica kernel_image) but during the boot up this new kernel is not showing as option.

Please help me
