How to Get Linux Kernel 6.8
The source tarball of the new kernel release is available to download at Kernel.org:
Ubuntu Team is maintaining Mainline Kernel PPA contains the deb packages for testing purpose. The recent versions however can only install on Ubuntu 23.10 and higher, due to dependency issue.
For Ubuntu 22.04, Ubuntu 20.04, and Debian 12, there’s a third-party repository maintained by ex core developer from Ubuntu. Though it usually updates for a new Kernel series some days later (mostly the date of first point release that kernel.org marks it as stable).
