pyenv BUILD FAILED - The Python ctypes extension was not compiled. Missing the libffi lib?

Question

This problem occurs when installing Python 3.6.8. But version 3.6.10 installs successfully.

pyenv install 3.6.8

First I installed Python dependencies and build tools from https://github.com/pyenv/pyenv/wiki#suggested-build-environment. Additionally installed libffi-dev: sudo apt-get install libffi-dev

This didn't solve the problem
