You likely have a version of python3.5 installed in /usr/local/bin.
Please remove that and then run 'sudo apt-get -f install.'

Title:
  While upgrading to 17.04: package python3 3.5.1-4 failed to
  install/upgrade: pre-dependency problem - not installing python3

Status in python3-defaults package in Ubuntu:
  Incomplete

Bug description:
  I got this error while upgrading from 16.10 to 17.04, along with the
  same Python traceback as below. After a reboot, I seem to now be on
  17.04.

  I had just successfully upgraded from 16.04 to 16.10 with no problems.

  When the error occurred, I was advised by a dialog to try the
  following command, which produced a very similar error, with
  traceback.

  $ sudo apt-get install -f
