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.

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:

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

1. linux-headers-6.2.0-060200-xxxxxx_all.deb
2. linux-headers-6.2.0-060200-generic_xxx_amd64.deb
3. linux-modules-6.2.0-060200-generic_xxx_amd64.deb
4. 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

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

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.1.6/amd64/linux-image-unsigned-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-image-unsigned-6.1.6-060106-generic_6.1.6-060106.202301141035_amd64.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 . var jetpackLazyImagesL10n = {"loading_warning":"Images are still loading. Please cancel your print and try again."};
