Install/Upgrade XanMod Kernel LTS on Rocky Linux 8

XanMod is a free, open-source general-purpose Linux Kernel alternative to the stock kernel that is on Rocky Linux. It features custom settings and new features and is built to provide a responsive and smooth desktop experience, especially for new hardware.

Installing a third-party kernel may be for you for users seeking to have their system kernel up to date and not wanting to install kernels or use the testing/unstable repositories manually.

Currently, the XanMod LTS kernel is supported and not the latest bleeding-edge using the rmnscnce/kernel-xanmod. 

For more information on XanMod Kernel before installing, visit the XanMod Kernel features information page.

In the following tutorial, you will learn how to install the latest XanMod Kernel on your Rocky Linux 8 server or workstation desktop.

Update your Rocky Linux operating system to make sure all existing packages are up to date:

sudo dnf upgrade --refresh -y

Update XanMod Kernel LTS

To keep the Linux kernel you installed with XanMod up to date, you will run the standard dnf update and upgrade commands.

To check for updates.

sudo dnf update

If an upgrade is available.

sudo dnf upgrade

Alternatively, users should be using the upgrade –refresh command, which is faster and more accurate.

sudo dnf upgrade --refresh

Remove (Uninstall) XanMod Kernel LTS

To remove XanMod Kernel, use the following command.

sudo dnf remove kernel-xanmod-lts

However, you will notice after rebooting that the XanMod kernel remains. To remove it in full from your system, you need to disable the repository, re-install the original kernel.

First, disable the Copr repository that XanMod was installed from.

sudo dnf copr disable rmnscnce/kernel-xanmod -y

Next, re-install the default kernel packages.

sudo dnf reinstall kernel*

Example output:

Next, reboot your PC.

Now back in your system, recheck the kernel version installed.

cat /proc/version

Example output:

Next, confirm that the original kernels are installed only using the rpm -qa command.

rpm -qa | grep `uname -r`
