How to Install Kernel 5.6 in Ubuntu / Linux Mint

upgrade Linux Kernel

Linux Kernel 5.6 was officially released. Linus Torvalds announced:

So I’ll admit to vacillating between doing this 5.6 release and doing another -rc.

This has a bit more changes than I’d like, but they are mostly from davem’s networking fixes pulls, and David feels comfy with them. And I looked over the diff, and none of it looks scary. It’s just slightly more than I’d have preferred at this stage – not doesn’t really seem worth delaying a release over.

So about half the diff from the final week is network driver fixlets, and some minor core networking fixes. Another 20% is tooling – mostly bpf and netfilter selftests (but also some perf work).

Linux Kernel 5.5 features WireGuard VPN support, and a lot of other notable improvements, including initial USB 4 support, Amazon’s Echo smart speaker, new Intel, AMD, and Arm hardware enablement.
