To whom it may concern https://github.com/edx/configuration/blob/master/util/balancecontainers.py line 105 print line is missing parentheses. This is causing errors when attemptig a native installation on ubuntu using [https://openedx.atlassian.net/wiki/spaces/OpenOPS/pages/146440579/Native+Open+edX+Ubuntu+16.04+64+bit+Installation
Hmm, this sounds very unusual. Can you pastebin the full installation log? It seems like you are somehow using Python 3 where the file was expecting Python 2.
That was my first thought too since this is a Python 3 vs Python 2 issue normally.
