A comprehensive guide on how to install a kernel1 on Arch Linux, including default, LTS, Zen, or Hardened kernels. Follow these easy steps to safely update your kernel.
Introduction
The kernel is the heart of any operating system. On Arch Linux, you have the flexibility to choose the kernel that fits your needs, from the default kernel to LTS (Long-Term Support), Zen, and Hardened kernels. In this article, we’ll guide you step by step through the process of installing different kernels on Arch Linux.
1. Update Arch Linux System
Before installing a new kernel, make sure your Arch Linux system is fully updated. This helps avoid package conflicts during the installation process.
sudo pacman -Syu
2. Find Available Kernels
To see the list of available kernels, use the following command:
pacman -Ss linux
Popular kernels available in Arch Linux include:
linux: The default kernel.linux-lts: A Long-Term Support kernel.linux-zen: A kernel optimized for performance and responsiveness.linux-hardened: A security-focused kernel.
3. Install Kernel
Choose the kernel that fits your needs. For example, if you want a more stable and long-term supported kernel, install the LTS kernel:
sudo pacman -S linux-lts
Or, if you want a high-performance kernel, install the Zen kernel:
sudo pacman -S linux-zen
4. Update Bootloader
After installing the kernel, update the bootloader to ensure the new kernel is recognized at boot. If you use GRUB, run the following command:
sudo grub-mkconfig -o /boot/grub/grub.cfg
5. Reboot System
Once everything is done, reboot your system to start using the new kernel:
sudo reboot
6. Verify the Kernel
After rebooting, check if the new kernel is active using the following command:
uname -r
Conclusion
By following the steps above, you can easily install a new kernel on Arch Linux, whether it’s the default, LTS, Zen, or Hardened version. Choose the kernel that best fits your needs to get the best performance and stability.
