And it is particularly bad timing. 23.10 was released yesterday, so a new kernel should roll into 22.04 soon. It would also fix most of the software complaints if the auther would have used 23.10.
Please save yourself from the hassle of compiling a kernel, especially for Ubuntu (the userspace _expects_ Ubuntu patches, e.g. for apparmor). Pick a distro with a recent release, and for Ubuntu in particular check if you can live with 2 upgrades a year until you reach the next LTS (April of even years, so right now the _next_ upgrade. Worst case is 3 upgrades).
