kernel-package 13.018+nmu1 (armhf binary) in ubuntu focal

 This package provides the capability to create a Debian kernel image
 package by just running make-kpkg kernel_image in a kernel source
 directory tree. It can also package the relevant kernel headers into
 a kernel-headers package. In general, this package is very useful if
 you need to create a custom kernel, if, for example, the default
 kernel does not support some of your hardware, or you wish a leaner,
 meaner kernel. It also scripts the steps that need be taken to
 compile the kernel, which is quite convenient (forgetting a crucial
 step once was the initial motivation for this package). Please look at
 /usr/share/doc/kernel-package/Rationale for a full list of advantages
 of this package.
