Import XanMod APT Repository on Debian 12, 11 or 10

Step 1: Update Debian Before XanMod Installation

Prior to the XanMod kernel installation, updating your Debian system is a necessary step. This update minimizes potential conflicts during the XanMod installation. To perform the update, run:

sudo apt update && sudo apt upgrade

This command refreshes your package lists and upgrades the packages to their latest versions.

Step 2: Install Required Initial Packages

Before installing the XanMod kernel, certain dependencies must be in place. These packages might already be installed, but to ensure their presence, execute:

sudo apt install software-properties-common apt-transport-https ca-certificates curl -y

This command installs key packages necessary for managing repositories and secure communication.

Step 3: Import the XanMod GPG Key and Repository

The first major step in installing the XanMod kernel is adding the XanMod repository to your system. Here, we’ll use the apt package manager for simplicity.

Import the XanMod GPG Key

Begin by importing the GPG key:

curl -fSsL https://dl.xanmod.org/gpg.key | gpg --dearmor | sudo tee /usr/share/keyrings/xanmod.gpg > /dev/null

This command retrieves the XanMod GPG key and integrates it into your system’s keyring, a crucial step for verifying the authenticity of the XanMod packages.

Add the XanMod Repository

Next, add the XanMod repository:

echo 'deb [signed-by=/usr/share/keyrings/xanmod.gpg] http://deb.xanmod.org releases main' | sudo tee /etc/apt/sources.list.d/xanmod-kernel.list

This command adds the XanMod repository to your APT sources, enabling you to install packages from it.

Verify the Repository Addition

To confirm the successful addition of the repository, use:

grep xanmod /etc/apt/sources.list.d/xanmod-kernel.list

A successful addition will produce an output resembling:

deb [signed-by=/usr/share/keyrings/xanmod.gpg] http://deb.xanmod.org releases main

Step 4: Update Packages List After Import

Now, update your APT repository source listing to include the newly added XanMod repository:

sudo apt update

Install XanMod Kernel on Debian 12, 11 or 10

Download and Prepare the XanMod Kernel Check Script

To align the XanMod Kernel with your system’s CPU, begin by acquiring the XanMod Kernel Check Script. This script is instrumental in identifying the most compatible XanMod Kernel package for your Debian system.

Execute the following commands to download the script and modify its permissions:

wget https://dl.xanmod.org/check_x86-64_psabi.sh
chmod +x check_x86-64_psabi.sh

This step is crucial because the XanMod Kernel comes in various versions like linux-xanmod-x64v1, x64v2, x64v3, and x64v4. Each version is specifically optimized for different CPU architectures.

The script’s output will display the compatible x86-64 version. For instance, you might see:

CPU supports x86-64-v2

Your CPU might support different versions like x86-64-v1, v3, or v4, as indicated by the script.

Install the XanMod Kernel Using APT

Once you have identified the correct version, proceed to install the XanMod Kernel. For example, if your CPU supports x86-64-v2, the installation command would be:

sudo apt install linux-xanmod-x64v2

Remember to adjust the command based on the CPU version (v1, v3, or v4) that you determined earlier.

Verify XanMod Kernel Installation on Debian 12, 11, or 10

Confirming the XanMod Kernel Installation

After restarting your Debian system, it’s important to confirm the successful installation of the XanMod Kernel. This verification step ensures that your system is running the new kernel.

Check the Installed Kernel Version

To verify the installed kernel version, execute:

cat /proc/version

This command will output the currently active kernel version. If the installation was successful, the output will display the XanMod kernel version.

Example of Kernel Verification

Using additional tools like Neofetch can provide a more detailed view of your system information, including the kernel version.

Managing XanMod Kernel on Debian 12, 11 or 10

Update XanMod Kernel on Debian

After adding the XanMod APT repository, you can update the kernel just like any other package. Use the following command to check for updates and apply them:

sudo apt update && sudo apt upgrade

This command refreshes your package list and upgrades your system to the latest kernel version available in the XanMod repository.

Remove XanMod Kernel from Debian

Step 1: Remove the XanMod Source from the Repository

To begin removing the XanMod Kernel, first delete its source from your repository list:

sudo rm /etc/apt/sources.list.d/xanmod-kernel.list

This command removes the XanMod repository, preventing future updates from being fetched.

Step 2: Remove the GPG Key

If you do not intend to use XanMod in the future, it’s a good security practice to remove its GPG key:

sudo rm /usr/share/keyrings/xanmod.gpg

This step ensures the security integrity of your system by removing external authentication keys.

Step 3: List Installed XanMod Kernel Packages

Identify the XanMod Kernel packages installed on your system:

dpkg --list | grep `uname -r`

This command lists all XanMod Kernel packages associated with your current running kernel.

Step 4: Remove the XanMod Kernel Packages

To remove the identified XanMod Kernel packages, execute:

sudo apt remove linux-image-*.*.*-xanmod* linux-headers-*.*.*-xanmod* --purge

This command purges XanMod Kernel packages from your system.

Step 5: Restart Your System

Reboot your computer to apply the changes:

reboot

This step is crucial to switch back to the default kernel.

Step 6: Verify the Installation Rollback

After rebooting, confirm that the XanMod Kernel has been successfully removed and the default Debian kernel is active:

cat /proc/version

The output should display the default Linux Kernel version, indicating a successful rollback to the standard Debian kernel.

Conclusion: Installing XanMod Kernel on Debian

The XanMod Kernel is valuable to Debian Linux systems, offering various optimizations and improvements over the generic kernel. It provides enhanced performance, lower latency, and support for the latest CPU generations and features. By carefully selecting and installing the appropriate XanMod Kernel version, Debian users can experience a more responsive and optimized system.
