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. Brian.
