[SOLUTION]

1. Install lzma backport https://pypi.org/project/backports.lzma
2. edit /usr/local/lib/python3.7/lzma.py file for enabling this previously installed lib

try:
        from _lzma import *
        from _lzma import _encode_filter_properties, _decode_filter_properties
except ImportError:
        from backports.lzma import *
import _compression

3. Test volatility with libzma backports
