#### Why I did it
Build failed.
Due to the error message looks like build failed because `pyversions` utility was not found.
`pyversions` utility is a part of `python2-minimal` package and it wasn't installed.
#### How I did it
To avoid installing python2 just specify explicit python version `--with python3` and use build system for py3 `--buildsystem=pybuild`
#### How to verify it
Run build
This patch upgrade the kernel from version
4.9.0-9-2 (4.9.168-1+deb9u3) to 4.9.0-11-2 (4.9.189-3+deb9u2)
