boost fail to be detected / No 'bootstrap.jam' was found by searching for / file STRINGS file "/usr/include/boost/version.hpp" cannot be read.

I try to install qbittorent that requires boost library.

I tried to install boost from source successfully
(1.83)

sudo ./bootstrap.sh --prefix=/usr/local
and
sudo ./b2 install  --prefix=/usr/local

then... in outside the folder

b2 --version
Unable to load B2
-----------------
No 'bootstrap.jam' was found by searching for:

Please consult the documentation at 'https://www.bfgroup.xyz/b2/'.

but ...

cd ~/Downloads/_LINUX_PKGS/boost_1_83_0/tools/build$
b2 --version
B2 4.10-git

I had an directory of boost in usr/include that was detected from qbittorent and delete it.
But it tries to look into that directory...

Then i downlaoded the experimental package of libboost-all-dev_1.81.0.1~exp1_amd64.deb

and installed it with ``dpkg -i libboost-all-dev_1.81.0.1~exp1_amd64.deb` succesfully.
yet, b2 --version is not detecting boost library nor qbittorent (boost setup) detect it.

even export BOOST_BUILD_PATH=/home/elias/Downloads/_LINUX_PKGS/boost_1_83_0/tools/build/;b2 does not produce results

My system is linux bookworm

weirdly, no bootstrap.jam of boost 1.83 was detected here

The below paths from what file/files are got?
it is right to add somewhere /usr/share/boost-build/src/kernel/bootstrap.jam ?
The b2options for config file dont work at all
