Method 1: Installing Kernel Headers using apt-get

This method utilizes Ubuntu’s package manager, apt-get, to install kernel headers with just a few simple commands.

Step 1: Update Your System

Before proceeding, it is always a good practice to update your system to ensure that you have the latest package information. Open a terminal and type the following command:

$ sudo apt-get update

Step 2: Identify Your Current Kernel Version

To install the appropriate kernel headers, you need to know your current kernel version. Execute the following command to retrieve this information:

$ uname -r

Step 3: Install Kernel Headers

Now that we have our kernel version, we can proceed with installing the corresponding kernel headers. Enter the following command, replacing ‘<kernel-version>’ with your actual kernel version:

$ sudo apt-get install linux-headers-<kernel-version>

Step 4: Verify the Installation

To validate the successful installation of the kernel headers, run the following command:

$ dpkg -s linux-headers-<kernel-version>

Method 2: Manual Installation from Kernel.org

For users who require a specific version of kernel headers not available in the default repositories, this method provides a clever workaround by manually installing the headers directly from the official Kernel.org website.

Step 1: Visit the Kernel.org Website

Open your web browser and navigate to https://www.kernel.org. Locate the ‘Download’ section and find the desired kernel version with matching headers. Click on the appropriate link to initiate the download.

Step 2: Extract the Downloaded Archive

Once the download is complete, navigate to the downloaded file’s location and right-click on it. Select ‘Extract Here’ to extract the archive contents to a new folder.

Step 3: Enter the Kernel Header Directory

Open a terminal and navigate to the extracted kernel source directory. This will typically be named with the following format: linux-<kernel-version>/.

Step 4: Configure and Install the Kernel Headers

To configure and install the kernel headers, run the following series of commands:

$ sudo apt-get install build-essential
$ sudo make mrproper
$ sudo make menuconfig (optional - for advanced users)
$ sudo make
$ sudo make modules_install
$ sudo make install_headers
