How To Install Kernel 6.14 RC7 On Ubuntu, Debian And Derivative Systems

The Linux kernel is the core component of any Linux operating system, managing hardware resources and system processes.

The latest version available of the Kernel 6.14 branch is Kernel 6.14 RC7, which comes with changes.

The official announcement:

“Things continue to look quite calm, and I expect to release the final 6.14 next weekend unless something very surprising happens.

In the meantime, I’ve pushed out rc7, and while it all looks nice and small and safe (the biggest patches in here are some selftest updates, and a few smallish reverts – but there’s tiny noise all over the place), it would be good to get one final week of good testing in. So please give it a whirl.”

Kernel 6.14 RC7 main highlights

AMDXDNA Driver: A new driver supporting Ryzen AI Neural Processing Units (NPUs) has been integrated, enhancing AI capabilities on AMD platforms.
Networking Improvements: The update includes numerous wired and wireless driver enhancements, benefiting a wide range of network hardware.
Btrfs File-System Enhancements: An experimental RAID1 round-robin read mode has been introduced, offering more balanced read operations across devices.
AMD CPU Performance: The ‘cpupower’ utility now offers improved support for AMD processors, aiming to enhance performance and power management.
Graphics Driver Updates: Additional AMDGPU changes have been incorporated, including bug fixes and preparations for upcoming RDNA4 graphics.

In this article I will show you how to install Kernel 6.14 RC 7 on Ubuntu, Linux Mint and derivative systems.

Check your current kernel version:

Before proceeding with the installation, verify your current kernel version by running:

How to install Kernel 6.14 RC 7 on Ubuntu, Linux Mint, Debian, and derivative systems (amd64/x86_64):

Step 1: Update Your System

Run the following commands to ensure your system is up to date:

sudo apt update && sudo apt upgrade -y

This will update your package list and upgrade all installed packages to their latest versions.

What Does apt update Do?
This command updates the package list to reflect the latest versions available from your repositories.
What Does apt upgrade Do?
It upgrades all the packages that have new versions available while keeping existing dependencies intact.

Step 2: Download the Kernel 6.14 RC 7 Packages

Download the necessary kernel packages from the official Ubuntu repositories or the kernel website:

wget -c https://kernel.ubuntu.com/mainline/v6.14-rc7/amd64/linux-headers-6.14.0-061400rc7-generic_6.14.0-061400rc7.202503170040_amd64.deb
wget -c https://kernel.ubuntu.com/mainline/v6.14-rc7/amd64/linux-headers-6.14.0-061400rc7_6.14.0-061400rc7.202503170040_all.deb
wget -c https://kernel.ubuntu.com/mainline/v6.14-rc7/amd64/linux-image-unsigned-6.14.0-061400rc7-generic_6.14.0-061400rc7.202503170040_amd64.deb
wget -c https://kernel.ubuntu.com/mainline/v6.14-rc7/amd64/linux-modules-6.14.0-061400rc7-generic_6.14.0-061400rc7.202503170040_amd64.deb

Step 3: Install the New Kernel

Install the downloaded packages using dpkg:

sudo dpkg -i linux-headers-6.14*.deb linux-modules-6.14*.deb linux-image-6.14*.deb

Step 4: Update GRUB and Reboot

Once the kernel installation is complete, update GRUB to ensure the new kernel is recognized:

Regenerate the GRUB Configuration

Run the following command to update GRUB with the latest installed kernel:

sudo update-grub

Verify GRUB Configuration

To confirm that the new kernel has been detected, check the GRUB configuration:

cat /boot/grub/grub.cfg | grep 'menuentry'

This should list all available kernels, including Kernel 6.14 RC7.

Reboot the System

Restart your computer to apply the changes:

sudo reboot

Select the New Kernel (if needed) – If the system doesn’t automatically boot into the new kernel, you can manually select it:
- Hold Shift or Esc during boot to access the GRUB menu.
- Navigate to Advanced options for Ubuntu.
- Choose the entry with Kernel 6.14 RC7.
- Press Enter to boot.

Verifying the Installed Kernel

After rebooting, confirm the new kernel version:

uname -r

Rolling Back to a Previous Kernel

If you encounter issues with the new kernel, you can revert to an older version:

Reboot and Access the GRUB Menu – Restart your system and hold Shift or Esc to enter the GRUB boot menu.
Select Advanced options for Ubuntu – Choose an older kernel version and boot into it.
Remove Kernel 6.14 RC7 (if desired) – If you prefer to remove the new kernel permanently, run:

sudo apt remove linux-headers-6.14* linux-modules-6.14* linux-image-6.14*
sudo update-grub
sudo reboot

Conclusion

With Linux 6.14-rc7, the kernel is nearing its final release, bringing significant improvements across various subsystems.

From enhanced AI support with the AMDXDNA driver to networking optimizations and better file system handling, this update strengthens Linux’s performance and hardware compatibility.

The refinements in AMD CPU power management and graphics drivers further ensure a smoother experience for users. If no major issues arise, we can expect the stable release soon, solidifying these advancements in the Linux ecosystem.
