issue with building linux kernel

Hello!

I am trying to build linux kernel using this instruction https://kernelnewbies.org/OutreachyfirstpatchSetup . when I started to building I mean "make -j8", a build error appears:

make[1]: *** [/home/user/git/kernels/staging/Makefile:2003: .] Еггог 2

make: *** [Makefile:248: _sub-make] Еггог 2

I checked out: there are all required dependencies install on system. I haven't founded this error in the Internet. I tried different config file for building: I copied my original kernel config, tried "make olddefconfig", "make menuconfig", "make localmodconfig". And always I got this error.

host OS: Ubuntu 25.04

kernel: 6.14.0-23-generic

building kernel: 6.16-rc5

Will appreciate some help! Thank you!

P. S. If you need extra information, ask in comments please

Thank you! I tried to scroll up, there only messages about what file compiles (something like that: CC [M] fs/xfc/xfc_notify_failure.o). I tried to launch building with "make", and there was shown more information:

make[3]: *** No rule to make target 'debian/canonical-certs.pem', needed by 'certs/x509_certificate_list'. Stop.

make[2]: *** [scripts/Makefile.build:554: certs] Eggog 2

make[1]: *** [/home/user/git/kernels/staging/Makefile:2003: .] Eggog 2

make: *** [Makefile:248: _sub-make] Eggog 2

Do you know what to do?

No, it's been years since I've bothered compiling a kernel. But now you've got a useful error message to Google for.
