Linus Torvalds announced the release of Kernel 6.5 this Sunday. He wrote:

So nothing particularly odd or scary happened this last week, so thereis no excuse to delay the 6.5 release.

I still have this nagging feeling that a lot of people are on vacation and that things have been quiet partly due to that. But this release has been going smoothly, so that’s probably just me being paranoid. The biggest patches this last week were literally just to our selftests.

Linux Kernel 6.5 features enhanced load balancing for Intel hybrid CPUs, Intel SoundWire ACE2.x support, and new meteor Lake-S driver.

For AMD, it now uses AMD P-State driver by default rather than CPUFreq for Zen 2 and newer systems, and support Error Detection And Correction (EDAC) subsystem for AMD Ryzen 7000 series.

The AMDGPU driver enabled FreeSync video mode by default, got performance improvements and power saving optimizations.

The release also improved LoongArch support with Simultaneous Multi-Threading, SIMD/Vector Extensions. Added support for the Alibaba T-Head TH1520 RISC-V 64-bit processor, and IBM POWER10 received DEXCR support.

Other changes in Kernel 6.5 include:

• Mainline support for the Acer Aspire 1 Arm laptop, Sony Xperia M4 Aqua phone.
• Enable new Permission Indirection Extensions for Armv8.9
• Open-source driver support for Adreno 690 that found in Lenovo ThinkPad X13s laptop.
• Mediatek Vcodec driver has added support for AV1 and HEVC/H.265 stateless video codecs.
• Much faster parallel direct I/O overwrite on EXT4.
• Microsoft Xbox controller rumble support
• Initial support for USB4 v2.
• MIDI 2.0 support

How to Install Linux Kernel 6.5 in Ubuntu

As usual, the mainline Kernel PPA build the packages available to download at the link below:

Sadly, this build only installs in Ubuntu 23.10 due to dependency updates. For modern 64-bit (x86_64) PC/laptop, select download the amd64 build packages:

1. linux-headers-6.5.0-060500-xxxxxx_all.deb
2. linux-headers-6.5.0-060500-generic_xxx_amd64.deb
3. linux-modules-6.5.0-060500-generic_xxx_amd64.deb
4. linux-image-unsigned-6.5.0-060500-generic_xxx_amd64.deb

After downloading them, right click on blank area in Downloads page and select “Open in Terminal”. Finally, install the kernel packages via command:

sudo apt install ./linux*.deb

For Ubuntu 22.04, Kernel 6.5 is available to install by running sudo apt install linux-oem-22.04d command in terminal.

Ubuntu 20.04 user can install it through the new zabbly repository.

For those who want to install the latest Linux Kernel (6.11.x updated), there’s a new apt repository made for Ubuntu 20.04, Ubuntu 22.04, Ubuntu 24.04 and Debian 12 Bookworm.

As you may know, Ubuntu has a mainline Kernel PPA that keeps building the latest Linux Kernel packages for testing purpose. The most recent packages however do NOT support current Ubuntu 22.04 & 20.04 LTS.

For those who need the latest Kernel for new hardware support or compatibility fixes, there’s now a new repository with all current Ubuntu LTS (20.04 & 22.04) and Debian Stable (Bookworm) support.

It’s maintained by Stéphane Graber, Ubuntu core developer and project leader of Linux containers(@lxc), who quit from Canonical last month, after working for the company for 12 years.

And, he made this repository because Ubuntu’s generic kernel that he thought has sadly decreased in quality over time.

The Ubuntu kernel includes a lot of backported fixes and occasionally, those backports go bad, resulting in missing commits, introducing bugs and regressions. Unfortunately the way the Ubuntu kernel is built, tested and published comes with a lot of delays, making fixing such regressions often take weeks if not months

Install Latest Kernel in Ubuntu via new Repository

NOTE 1: This is a trustworthy, but unofficial repository!
NOTE 2: Like Ubuntu Mainline Kernel PPA, the packages are un-signed, you may need to turn off Secure Boot to boot the new kernel.

First, open terminal either from start menu or ‘Activities’ overview.

1. Install the GPG Key

When terminal opens, first run command to create ‘/etc/apt/keyrings’ directory, in case it does not exist:

sudo mkdir -p /etc/apt/keyrings

Then, run command to download the key and install to that directory you just created:

sudo wget -O - https://pkgs.zabbly.com/key.asc |sudo tee /etc/apt/keyrings/zabbly.asc

2. Set up the source repository

Then, run command below to create & edit the source file:

sudo gedit /etc/apt/sources.list.d/zabbly-kernel-stable.sources

Depends on your desktop environment, replace gedit with gnome-text-editor for Ubuntu 24.04, Debian 12 GNOME, mousepad for XFCE, or use nano that works in most Linux.

When terminal opens, add following lines and save it:

Enabled: yes
Types: deb deb-src
URIs: https://pkgs.zabbly.com/kernel/stable
Suites: jammy
Components: main
Architectures: amd64
Signed-By: /etc/apt/keyrings/zabbly.asc

NOTE: You have to replace jammy (for 22.04, Linux Mint 21) in the code with

• noble for Ubuntu 24.04, Linux Mint 22.
• focal for Ubuntu 20.04
• or bookworm for Debian 12.

Also, replace amd64 with arm64 for ARM devices, such as Raspberry Pi. For nano text editor, press Ctrl+S to save, then Ctrl+X to exit.

3. Update package cache & Install Newest Kernel

When done setting up the new source repository and GPG key, run the command below to re-index system package cache:

sudo apt update

Finally, install the latest kernel, 6.11.x so far, by running command:

sudo apt install linux-zabbly

Tips: the repository also contains the Kernel 6.7, 6.8, 6.9, and 6.10 packages. To install one of them, Kernel 6.8 for example, use command:

sudo apt install linux-headers-6.8.10-zabbly+ linux-image-6.8.10-zabbly+

The minor version number varies as time is going. Type the first half of the last command (sudo apt install linux-headers-6.8) and hit Tab to list all available choices.

4. Verify

Finally, restart your machine and run the command below to verify your Kernel version in terminal:

uname -a

Uninstall:

If you have any issue with the new Kernel, just restart and select boot an old Kernel from Grub menu under ‘Advanced Options’.

Then, run the command below to remove the Kernel from Zabbly repository:

sudo apt remove --autoremove linux*zabbly*

Depends on when you tried this tutorial, the package version varies. So, I use asterisk wildcard in command to auto-select any package start with ‘linux‘ and have ‘zabbly‘ in between of package name. Just in case, it’s better to keep an eye on terminal output before hitting ‘y’ to confirm.

Also, remove the source repository by running commands below to delete the key and source file:

sudo rm /etc/apt/sources.list.d/zabbly-kernel-stable.sources

sudo rm /etc/apt/keyrings/zabbly.asc

Finally, run sudo apt update to refresh system package index.

Linux Kernel 6.4 was released a few days ago. Ubuntu users can now install it from Kernel Mainline PPA.

Linux Kernel 6.4 features initial Apple M2 processors support, Realtek rtl8710bu/rtl8188gu, rtl8822bs, rtl8822cs and rtl8821cs WiFi hardware support, Turtle Beach and Qanba gaming controller support, and many Kye/Genius drawing tablets, such as EasyPen M406 / M506 / M406W, EasyPen 340, MousePen 508WX / 508X, and PenSketch T609A.

sudo apt remove --autoremove linux-headers-6.4.0-060400 linux-modules-6.4.0-060400-generic

Linus Torvalds announced the release of Linux Kernel 6.4 few days ago on Sunday. He wrote:

Hmm. Final week of 6.4 is done, and we’ve mainly got some netfilter fixes, some mm reverts, and a few tracing updates.

There’s random small changes elsewhere: the usual architecture noise, a number of selftest updates, some filesystem fixes (btrfs, ksmb), etc.

…

The new kernel brings many new devices support. They include initial Apple M2 processors support, Realtek rtl8710bu/rtl8188gu, rtl8822bs, rtl8822cs and rtl8821cs WiFi hardware support, Turtle Beach and Qanba gaming controller support, and many Kye/Genius drawing tablets, such as EasyPen M406 / M506 / M406W, EasyPen 340, MousePen 508WX / 508X, and PenSketch T609A.

How to Get Linux Kernel 6.4

The source tarball for the new Kernel release is available to download at the official website:

For Ubuntu users, see Mainline Kernel PPA seems broken and their’s no Kernel 6.4 build at the moment, perhaps due to this issue. So, building from source code could be the only way so far to get the latest Kernel in Ubuntu.

Linux Kernel 6.2 was release this Sunday. Linus Torvalds announced it at lkml.org:

So here we are, right on (the extended) schedule, with 6.2 out.

Nothing unexpected happened last week, with just a random selection of small fixes spread all over, with nothing really standing out. The shortlog is tiny and appended below, you can scroll through it if you’re bored.

Wed have a couple of small things that Thorsten was tracking on the regression side, but I wasn’t going to apply any last-minute patches that weren’t actively pushed by maintainers, so they will have to show up for stable. Nothing seemed even remotely worth trying to delay things for
…

What’s New in Kernel 5.16

• Initial support for NVIDIA RTX 30 “Ampere” GPU accelerated graphics with Nouveau open-source driver.
• Intel Arc graphics support being stable and enabled out-of-the-box!

For those who want to try out the latest Linux Kernel 6.1.x, the Mainline Kernel PPA finally works again.

Ubuntu developer team maintains the Mainline Kernel PPA with latest Kernel packages. It however failed to build for all the Kernel releases since v6.0.10.

After more than a month until the release of Kernel 6.1.4, the maintainers finally fixed the issue and built the kernel packages correctly for Ubuntu 22.04 +.

How to Install Kernel 6.1.x in Ubuntu 22.04

NOTE: Mainline Kernels are built for testing purpose! They are not supported and are not appropriate for production use. Use them at your own risk

Unlike normal Ubuntu PPAs, there’s no need to add the Mainline PPA into system repository. Just download the .deb packages from the repository page and install them.

1. At the moment of writing, the latest version is Kernel 6.1.6, available to download at the link below. For other versions, go to this page.

For modern 64-bit computer/laptop, select download the top 4 amd64/build packages. For arm64 devices, download the 3 of next 6 packages (either with or without 64k). There are as well the packages for armhf, ppc64el, and s390x available to download.

Or, user can run commands below one by one in terminal to download the packages (64-bit only):

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.1.6/amd64/linux-headers-6.1.6-060106-generic_6.1.6-060106.202301141035_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.1.6/amd64/linux-headers-6.1.6-060106_6.1.6-060106.202301141035_all.deb

2. After downloading the packages, install them via apt command.

If you downloaded the packages via web browser link, you may first open the Downloads folder in file manager. Then, right-click on blank area and select “Open in Terminal” first to open that folder as working directory in terminal.

Finally, run command to install all .deb packages in the folder:

sudo apt install ./*.deb

3. When done, restart your machine and verify your kernel via command:

uname -a

NOTE: Mainline Kernels are not signed. You may need to disable Secure Boot in BIOS to make it work.

Uninstall Kernel 6.1.x

For any reason, you can easily remove the Kernel by doing following steps.

1. Firstly, reboot and select the old Kernel in boot menu under “Advanced Options for Ubuntu”.

2. Open terminal (Ctrl+Alt+T), and run command to remove Kernel you just installed (change version number accordingly):

sudo apt remove --autoremove linux-modules-6.1.6-060106-generic linux-headers-6.1.6-060106

Tip: you may type linux-modules-6 and hit Tab key to auto-complete the package name. Also type linux-headers-6 and hit Tab for the second.

Linux Kernel 6.0 was released hours ago! Here are the new features and how to install instructions for Ubuntu 22.04.

“So, as is hopefully clear to everybody, the major version number change is more about me running out of fingers and toes than it is about any big fundamental changes.” Linus Torvalds announced.

New Features in Linux Kernel 6.0

The new kernel introduced experimental support of Intel’s A750 and A770 graphics card, using i915 DRM kernel driver with “force_probe” option. PCI support for LoongArch CPU architecture from China and OpenRISC architecture.

Linux Kernel 5.19 was released! Ubuntu Mainline PPA has made the packages for testing purpose.

Linus Torvalds announced this kernel release last night:

On a personal note, the most interesting part here is that I did the release (and am writing this) on an arm64 laptop. It’s something I’ve been waiting for for a _loong_ time, and it’s finally reality, thanks
to the Asahi team. We’ve had arm64 hardware around running Linux for a long time, but none of it has really been usable as a development platform until now.

Linux 5.19 Kernel features initial support for LoongArch CPU architecture, Apple M1 NVMe controller and Apple eFuse driver. There are also initial graphics driver for Raptor Lake P (Intel’s 13th generation processors), In-Field Scan (IFS) to circuit level tests on a CPU core, and bug-fix for Intel laptops running hot and draining the battery faster.

Other features include:

• Zstd compressed firmware support
• Google Whiskers Touchpad support.
• Lenovo X12 trackpoint support.
• Armv9 Scalable Matrix Extension support
• Big TCP and pureLiFi’s device driver.

How to Install Kernel 5.19 in Ubuntu 22.04:

NOTE: The mainline kernel packages are NOT officially support! You install them ONLY for specific hardware support or testing purpose!

First, go to the PPA web page via the link button below:

Select download amd64/build package for modern PC/laptop, arm64/armhf build for ARM devices, or ppc64el/s390x depends on your CPU architecture type. And, install the packages in following order:

Then install them via command:

cd /tmp && sudo apt install ./*.deb

In addition, there’s a third-party graphical tool can do the job with a few clicks.

Install Kernel via third-party tool

After installation, restart your computer and verify by running command:

uname -a

How to Remove Kernel 5.18:

To remove this kernel from your system, firstly boot (re-boot) with the previous Kernel from ‘Grub menu -> Advanced options’.

When you’re in, run the command below in terminal (Ctrl+Alt+T) to remove the Kernel 5.18:

sudo apt remove --autoremove linux-headers-5.18.0-051800 linux-image-unsigned-5.18.0-051800-generic

For those sticking to the old Ubuntu 18.04, but need higher Linux kernel version for specific hardware support, here’s how to install the Linux Kernel 5.13 from Ubuntu 20.04 repository.

NOTE: Ubuntu 20.04’s kernel package does install and seems running good in Ubuntu 18.04. But I’m not sure if it will cause compatibility issues. Install it ONLY that you do require it, and use it at your own risk!!

Linux Kernel 5.13 features include:

• Initial and early support for Apple M1.
• New “Landlock” Linux security module.
• Initial graphics support for Alder Lake S.
• AMD FreeSync HDMI support.
• New Intel cooling driver
• Realtek RTL8156 and RTL8153D support
• New drivers support for Amazon’s Luna game controller.
• Apple Magic Mouse 2 support .
• Realtek RT1019, RT1316, RT711 and RT715 support.

Install Linux Kernel 5.13 in Ubuntu 18.04:

You know, the Mainline Kernel PPA maintains the latest kernel package. However, it’s now built against the most recent Ubuntu libc6 library.

The Kernel package from Ubuntu 20.04 repository could be the only way to get recent Kernels for Ubuntu 18.04, except for building by yourself.

1. Add Ubuntu 20.04 Updates repository:

Firstly, press Ctrl+Alt+T on keyboard to open terminal. When it opens, paste the command below and hit enter:

sudo sh -c 'echo "deb http://archive.ubuntu.com/ubuntu focal-updates main" >> /etc/apt/sources.list'

The command adds focal-updates repository to your system software sources.

2. Set lower priority for the repository:

Also in terminal window, run command to create and open a config file via Gedit text editor:

sudo gedit /etc/apt/preferences.d/99focal-updates

When the file opens, add following lines and save it:

Package: *
Pin: release a=focal-updates
Pin-Priority: 1

After that, your system will not automatically install updates from this repository, unless you do it manually.

3. Update package cache:

Before being able to install packages from that repository, refresh system cache via command:

sudo apt update

If you’re following this tutorial on 18.04 based system that missing GPG key, run the commands below one by one to get them:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3B4FE6ACC0B21F32

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 871920D1991BC93C

4. Install Kernel 5.13:

Finally install the 20.04’s kernel package via the command below. So far, it’s Kernel 5.13.

sudo apt install linux-generic-hwe-20.04

After installation, restart your PC and verify via command:

uname -a

How to Remove Kernel 5.13 from Ubuntu 18.04:

To remove the focal-updates repository, run command to edit software sources file:

sudo gedit /etc/apt/sources.list

When the file opens, remove or comment (add # at the beginning) the line of:

deb http://archive.ubuntu.com/ubuntu focal-updates main

After saved it, run sudo apt update to refresh the cache.

To remove Linux Kernel 5.13, you need to firstly restart and select boot with an old kernel (v5.4.x) from boot menu -> Advanced options.

Once you get into Ubuntu 18.04 with the previous Kernel, run the command below to remove Kernel 5.13:

sudo apt remove linux-image-5.13.0-37-generic linux-headers-5.13.0-37-generic linux-hwe-5.13-headers-5.13.0-37

NOTE: Ubuntu updates the kernel packages regularly, the package version may be different!! Change it to the one that you installed.
