Linux kernel 5.9 has been released! How to install on Ubuntu

Linux Kernel 5.9 was released a day ago.Linus Torvalds Presentation It:

To be honest, I was hoping for a lot less changes last week, but at the same time, there seems to be nothing particularly scary here. It’s more commits and modified lines than I wanted.

Most of this is a network fix I’ve already mentioned in the rc8 release notes last weekend. In fact, about half of the patches (and probably many of the commits) come from network-related things (both drivers and elsewhere).

Linux 5.9 includes early Intel Rocket Lake graphics, NVMe Zone Namebox (ZNS) support, 32-bit x86 Clang build support, and initial support for the Radeon RX 6000 “RDNA2” graphics card.

How to install Linux kernel 5.9 on Ubuntu: Mainline kernel Do not include drivers or patches provided by Ubuntu. These are not supported and are not suitable for production use.

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