Build/install custom linux kernel headers in ubuntu.

Linux Headers

• Install tools to build:

sudo apt-get update
sudo apt-get install kernel-package fakeroot wget bzip2

• Linux-2.6.39.1-linode34 is same as regular 2.6.39 source: http://forum.linode.com/viewtopic.phpt=6949&sid=cd983a6b71bb77bff08160fb55f67d12

cd ~/src
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.39.3.tar.bz2

• Build

tar xjf linux-2.6.39.3.tar.bz2
cd linux-2.6.39.3

# Restore config
zcat /proc/config.gz > .config

make-kpkg clean
fakeroot make-kpkg --initrd --append-to-version=-linode34 kernel_headers

• After it finishes compiling:

cd ..
sudo dpkg -i linux-headers-2.6.39.3-linode34_2.6.39.3-linode34-10.00.Custom_i386.deb
cd /usr/src
sudo ln -s linux-headers-2.6.39.3-linode34 linux-headers-2.6.39.1-linode34
cd /lib/modules/2.6.39.1-linode34
sudo ln -s /usr/src/linux-headers02.6.39.1-linode34 build

when I run : sudo dpkg -i linux-headers-2.6.39.3-linode34_2.6.39.3-linode34-10.00.Custom_amd64.deb
it report error:

The same thing happened to me, but after rebooting with the newly built kernel I was able to run sudo dpkg -i to install the custom headers.
