Hi Folks:

        According to the Build Guide for stx.2019.05, there is an error found in the building container,

/usr/lib/python2.7/site-packages/mockbuild/package_manager.py Line 162 will interrupt buiding

Process By throwing out an FileNotFoundError. While, FileNotFoundError is an Python3 built-in error,

not in python2.7. Just reporting to the community.
