How to get the latest Linux kernel on your Ubuntu box
For significant subcomponents of Ubuntu – and its derivatives – you don't need to wait for the next release to appear. You can upgrade major parts on the fly.
Here at Vulture Towers, we are working on a review of a machine with a 12th-generation Intel chip, and that's caused issues in some Linux distros. Back in 2021, we reported on work on kernel 5.16 to add Alder Lake support. Ubuntu 22.04 LTS shipped with kernel 5.15, though. The latest release, 22.10, includes the ageing kernel 5.19, which you also get in the latest update to "Jammy", 22.04.2.
