Actually, I have not checked the powerpc part by myself.


I just read the following page:

https://unix.stackexchange.com/questions/238469/difference-between-make-kpkg-and-make-deb-pkg


"make-kpkg is included in wheezy and jessie but stretch (current
stable) only contains it for powerpc.

Powerpc is no longer supported in buster (testing)"



I will drop the PowerPC part.

Hmm, OK.

I checked debian:buster in Docker,
and I see it.


root@...2de16960a:/home/foo# apt-file search  make-kpkg
kernel-package: /usr/bin/make-kpkg
kernel-package: /usr/share/man/man1/make-kpkg.1.gz
zsh-common: /usr/share/zsh/functions/Completion/Debian/_make-kpkg




If make-kpkg will still be included in the future Debian releases,
I'd like to change make-kpkg to make it work more reliably.


The git URL in the control file
"https://anonscm.debian.org/git/users/srivasta/debian/kernel-package.git"
seems stale.

Anyway, I found it in a new place:

$ git clone  https://salsa.debian.org/srivasta/kernel-package


Hmm, the last commit was three years ago.

So, it is almost unmaintained, I guess...

Probably, not fixed.

It is not stalled actually.
I guess make-kpkg is hiding messages sent to stdout for some reasons.
If you continue pressing "Enter" key,
it will move on to the build stage.

I will take a look if it should be maintained.



Anyway, I want to hear from Manoj.
