How do I obtain the offical Ubuntu patched kernel source without using git?

  • 772

I'm needing to custom compile a kernel to enable some very specific hardware features that are not on by default and have to be compiled in. I started following this guide but it seems to be slightly outdated for 12.04 onwards as some commands fail with missing source packages.

https://help.ubuntu.com/community/Kernel/Compile

What is the easiest way to rebuild the current kernel source so I can tweak the options I need?

12.04

  1. These steps are very general and apply to every package in Ubuntu/Debian.

    1. This will download the source package and applies all Ubuntu patches.

      apt-get source linux-image-3.... # select the exact package you want

    2. Install all build dependencies.

      sudo apt-get build-dep linux-image-3...

    3. Enter the directory of the source.

      cd linux-... # change accordingly

    4. Do the changes to the source you need.

    5. After finishing the edits, add a new version to the changelog (else it's going to complain the source doesn't match):

      dch --local mysuffix

    6. Build it with unsigned changes file and unsigned source package (for local testing):

      debuild -uc -us

      This will take a while!

    7. Find the packages one level below:

      ls -al ../*.deb

    8. Install them like any other package.
