So i decide again unpack all downloaded packages.

~/debs$ ls
libc6_2.36-9+deb12u9_amd64.deb      libc-bin_2.36-9+deb12u9_amd64.deb
libc6-dev_2.36-9+deb12u9_amd64.deb  libc-dev-bin_2.36-9+deb12u9_amd64.deb
~/debs$ sudo dpkg -i *.deb

And suddenly on this attempt there are successfully unpack without a problem.

Next step was ofcourse sudo apt install build-essential, and it is install successfully too.
