Linux Kernel 6.6 Now Easy to Install in Ubuntu 22.04/20.04 via Zabbly Repository

Last updated: November 13, 2023 — Leave a comment

For those who want to install the most recent Kernel 6.6 with new hardware support or compatibility fixes, it’s now available in the zabbly repository for Ubuntu 20.04, Ubuntu 22.04, and Debian 12.

Linux 6.6 was released few weeks ago as the latest Kernel series. It features PSR power saving for Intel 4th/5th CPU, initial PECI support for 4th Gen Xeon, initial support for the Intel Lunar Lake VPU4, Dynamic Boost Control support for AMD Ryzen laptops, as well as various new hardware support. See HERE for more.

As Ubuntu Mainline Kernel PPA is stuck at old RC5 for unknown reason, there’s NO official package for the new Kernel release.

For choice, the Zabbly repository maintained by Ubuntu core developer (quit a few months ago) has updated the new kernel package for Ubuntu 22.04 & 20.04.

Add Zabbly Repository & install latest Kernel

Press Ctrl+Alt+T on keyboard to open terminal. Then, run the commands below one by one to add the repository and install latest Kernel:

  • Download & install the key:
    sudo wget -O - |sudo tee /etc/apt/keyrings/zabbly.asc
  • Setup the repository via single command:
    sh -c 'cat <<EOF > /etc/apt/sources.list.d/zabbly-kernel-stable.sources
    Enabled: yes
    Types: deb
    Suites: $(. /etc/os-release && echo ${VERSION_CODENAME})
    Components: main
    Architectures: $(dpkg --print-architecture)
    Signed-By: /etc/apt/keyrings/zabbly.asc

    This is a single command for Ubuntu/Debian. For their based systems, you have to replace $(. /etc/os-release && echo ${VERSION_CODENAME}) with jammy (for 22.04 base), focal (for 20.04 base), or bookworm for Debian 12 base.

  • Finally, update & install the new kernel:
    sudo apt update
    sudo apt install linux-zabbly
