Linux Kernel 6.2 Released! How to Install in Ubuntu 22.04 / Linux Mint 21

Last updated: February 20, 2023 — 12 Comments

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!
Raspberry Pi 4K @ 60Hz display support.
New PlayStaion driver with Sony DualShock 4 controller support.
Added OneXPlayer senser and fan driver.
Dell Data Vault WMI driver.
Google Chrome OS Human Presence Sensor support
RealTek RT1318 and Rockchip RK3588 support.

How to Install Kernel 6.2 in Ubuntu 22.04+/Linux Mint 21

NOTE: The Mainline Kernel packages are not appropriate for production use. Only install it for testing purpose or for specific drivers.

The Mainline Kernel PPA has built the packages for Ubuntu and its based systems with modern 64-bit (amd64), arm64/armhf mobile, ppc64el and s390x CPU architecture types support.

User can select download the packages from the link page below:

Download Kernel 6.2 (.deb)

For modern 64-bit PC/laptop, they are:

linux-headers-6.2.0-060200-xxxxxx_all.deb
linux-headers-6.2.0-060200-generic_xxx_amd64.deb
linux-modules-6.2.0-060200-generic_xxx_amd64.deb
linux-image-unsigned-6.2.0-060200-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

Alternatively you can download and install the kernel packages via terminal commands ( open terminal via Ctrl+Alt+T):

cd /tmp/

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.2/amd64/linux-headers-6.2.0-060200-generic_6.2.0-060200.202302191831_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.2/amd64/linux-headers-6.2.0-060200_6.2.0-060200.202302191831_all.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.2/amd64/linux-image-unsigned-6.2.0-060200-generic_6.2.0-060200.202302191831_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.2/amd64/linux-modules-6.2.0-060200-generic_6.2.0-060200.202302191831_amd64.deb

sudo dpkg -i *.deb

Once installed, restart your computer and verify by running uname -a command in terminal!

Uninstall Linux Kernel 6.2:

Restart your machine and select boot with the previous kernel in boot menu under ‘Grub2 -> Advanced Option for Ubuntu’. Then run command to remove Linux Kernel 6.2:

sudo apt remove --autoremove linux-headers-6.2.0-060200 linux-modules-6.2.0-060200-generic

  Please note – this happens when attempting the install via sudo, as well as when attempting install as the root user

    This is a warning message that will happen every time you installing a local .deb package via apt package manager.
    
    It is a bug. It’s won’t affect the installing process, just skip it.

      Well…after receiving that message, and attempting to boot the kernel, the machine hangs at a initramfs prompt – 6.x kernel never boots. You’re saying that error has nothing to do with it.
      
      So I have 2 problems – the first on with the error is completely cosmetic from what you’re saying, the second, where the new kernel won’t boot – that seems more serious

  Ubuntu 23.04 come with Linux Kernel 6.2 out-of-the-box. Please verify by running command:
  
  uname -a

    You are correct that Ubuntu Mate 23.04 attempted to install the 6.2.0-20.20 kernel, but when online upgrade installation was finished, that kernel would not boot. It gave a dependency message that I could not understand. Therefore, I reset the running kernel to 5.19.0-40 (output of uname -a), which does boot. I have tried numerous times to install a more recent kernel but I keep getting a message about 6.2.0 having something missing.
