  • Qualcomm Adreno 405 / 640 / 650 open-source support.
  • AMDGPU TMZ support.
  • Intel Tiger Lake SAGV support.
  • New Arm SoC and platform support.
  • AMD Energy Driver.
  • Initial support for booting POWER10 processors.
  • Intel Tiger Lake Thunderbolt support for Intel’s Gateway SoCs.
  • And many other new features and improvements.

How to Install Linux Kernel 5.8 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

The mainline kernel packages for Linux 5.8 (64-bit) are now available for download at the link below:

Download Kernel 5.8

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

  1. linux-headers-5.8.0-xxxxxx_all.deb
  2. linux-headers-5.8.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  3. linux-modules-5.8.0-xxx-generic(/lowlatency)_xxx_amd64.deb
  4. linux-image-xxx-5.8.0-xxx-generic(/lowlatency)_xxx_amd64.deb

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

cd /tmp/

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/linux-headers-5.8.0-050800_5.8.0-050800.202008022230_all.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/linux-headers-5.8.0-050800-generic_5.8.0-050800.202008022230_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/linux-image-unsigned-5.8.0-050800-generic_5.8.0-050800.202008022230_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8/amd64/linux-modules-5.8.0-050800-generic_5.8.0-050800.202008022230_amd64.deb

sudo dpkg -i *.deb

Once installed, restart your computer and enjoy!

      Attention nvida users: you will have to add nvidia ppa in order to get drivers 450. OLd one won’t compile with 5.8

      A sincere Than You for a clear and accurate guide.
      Could you please augment it with:
      1. How to build the kernel from source?
      2. How to roll forward to the next release?

      Basically, the process of going from a download of a kernel source to bootable installation.
      Note: To me, building the .deb packages is secondary; All I have to worry about is one machine, 2-3 at the most.

      Thank you

      outdated, 5.8 is supported (in Mint so I presume in Ubuntu) from today.
