Comment 11 for bug 1682934

I too removed the references from /usr/local/lib and also from
/usr/local/bin and ran the 'sudo apt-get -f install' and it fixed
everything, including re-installing and configuring Python 3.5.

I suspect I caused the problem by manually installing Python to get
around the missing library problem I got when trying to run
'Transmageddon' so it points to a Python installer issue rather than
Ubuntu per se.

Interestingly if I type 'python' in a Terminal window it says I have
version 2.7.13 installed, even after the fix and update. Typing
'python3' says 3.5.3 is installed with a slightly earlier date than the
2.7 version.
