Linux Kernel 5.10 was released a day ago as the latest LTS (Long Term Support) release. Here’s how to install in Ubuntu & Linux Mint.

Linus Torvalds announced the release of Kernel 5.10: “Ok, here it is – 5.10 is tagged and pushed out. I pretty much always wish that the last week was even calmer than it was, and that’s true here too. There’s a fair amount of fixes in here, including a few last-minute reverts for things that didn’t get fixed, but nothing makes me go “we need another week”. Things look fairly normal.

Kernel 5.10 features include:

  • New hardware support including Intel Rocket Lake and Alder Lake
  • AMD Zen 3 temperature monitoring support.
  • Raspberry Pi VC4 support
  • The Creative Labs SoundBlaster AE-7 sound card support.
  • Nintendo Switch controller support
  • Initial support for NVIDIA Orin.
  • AMDGPU DC display support for GCN 1.0 (Southern Islands) GPUs.
  • And much more other changes.

How to Install Linux Kernel 5.10 in Ubuntu:

The mainline build kernels do not include any Ubuntu-provided drivers or patches. They are not supported and are not appropriate for production use.

For a graphical tool to install mainline kernel packages, try Ubuntu Mainline Kernel Installer.

The mainline kernel packages for Linux 5.10 (64-bit) are now available for download at the link below:

Download Kernel 5.10

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio):

  1. linux-headers-5.10.0-xxxxxx_all.deb
  2. linux-headers-5.10.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  3. linux-modules-5.10.0-xxx-generic(/lowlatency)_xxx_amd64.deb

Linux Kernel 5.9 was released a day ago. Linus Torvalds announced that:

Ok, so I’ll be honest – I had hoped for quite a bit fewer changes this last week, but at the same time there doesn’t really seem to be anything particularly scary in here. It’s just more commits and more lines changed than I would have wished for.

The bulk of this is the networking fixes that I already mentioned as being pending in the rc8 release notes last weekend. In fact, about half the patch (and probably more of the number of commits) is from the networking stuff (both drivers and elsewhere).

Linux 5.9 features initial Intel Rocket Lake graphics, NVMe zoned namespaces (ZNS) support, 32-bit x86 Clang build support, initial support for Radeon RX 6000 “RDNA 2” graphics cards, and more.

How to Install Linux Kernel 5.9 in Ubuntu:

The mainline kernels do not include any Ubuntu-provided drivers or patches. They are not supported and are not appropriate for production use.

For a graphical tool to install updated kernel package, try Mainline.

Linux Kernel 5.5 was announced two days ago. Linus Torvalds wrote on lkml.org:

So this last week was pretty quiet, and while we had a late network update with some (mainly iwl wireless) network driver and netfilter module loading fixes, David didn’t think that warranted another -rc. And outside of that, it’s really been very quiet indeed – there’s a panfrost driver update too, but again it didn’t really seem to make sense to delay the final release by another week.

Kernel 5.5 release highlights:

  • Support for the Broadcom BCM2711 SoC (Raspberry Pi 4).
  • New Logitech driver for G15 and G510 keyboard.
  • KVM support for IBM POWER secure guests/VMs.
  • Initial Intel Jasper Lake support.
  • Intel 5-level paging support is enabled by default
  • AMD OverDrive overclocking for Navi GPUs.
  • and much more other changes.

Linus Torvalds announced the 5.4 Kernel on lkml.org:

Linux Kernel 5.3 was released yesterday. Linus Torvalds announced that:

So we’ve had a fairly quiet last week, but I think it was good that we ended up having that extra week and the final rc8.

Even if the reason for that extra week was my travel schedule rather than any pending issues, we ended up having a few good fixes come in, including some for some bad btrfs behavior. Yeah, there’s some unnecessary noise in there too (like the speling fixes), but we also had several last-minute reverts for things that caused issues.

One _particularly_ last-minute revert is the top-most commit (ignoring the version change itself) done just before the release, and while it’s very annoying, it’s perhaps also instructive.

Linux 5.3 kernel brings many exciting changes including initial Intel HDR display support, Intel Speed Select support, Radeon RX 5700 Navi series support, better Intel Icelake Gen 11 graphics support, ACRN guest hypervisor support.
