You Can Now Install Linux Kernel 6.3 on Ubuntu, Here’s How
Released over the weekend by Linus Torvalds, Linux kernel 6.3 has already landed in Ubuntu’s official Mainline Kenrel Archive and it’s available for all Ubuntu users and supported on amd64 (x86_64), AArch64 (ARM64), ARMhf, PowerPC 64-bit Little Endian (ppc64el), and IBM System z (s390x) architectures.
I’ve only tested Linux kernel 6.3 on a fresh Ubuntu 23.04 (Lunar Lobster) installation and everything went smoothly. Of course, you can install it on any supported Ubuntu release, such as Ubuntu 22.10 (Kinetic Kudu) or Ubuntu 22.04 LTS (Jammy Jellyfish).
