how to build kernel from source without using cranky

[jkr0103]

Describe the support request

I am facing multiple issue with downloading the kernel source using cranky, e.g.:

$ kteam-tools/cranky/cranky chroot create-base "noble"
......
......

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

On another machine this command passes but fails at kteam-tools/cranky/cranky checkout noble:linux-intel

Hence wanted to know the other ways to download the kernel source and build it.

This is likely to be a temporary issue, just did the full process in a clean noble VM without issue.
You can find another guide without using cranky, please note that you will have to be on noble to build noble kernel: https://canonical-kteam-docs.readthedocs-hosted.com/en/public/how-to/build-kernel.html

Thanks, will try that!
