how to get pip to uninstall packages

[Skaperen]

i am getting errors like these:

Output:
Cannot uninstall 'apturl'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
Cannot uninstall 'bottle'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
Cannot uninstall 'Brlapi'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
Cannot uninstall 'command-not-found'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
Cannot uninstall 'docutils'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
Cannot uninstall 'fail2ban'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

Cannot uninstall 'onboard'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

there are many more when i feed its list of packages to pip uninstall commands.

and when i install Ubuntu package python3-pip then do pip3 install --upgrade pip it acts like this:

Output:
Collecting pip

Installing collected packages: pip
  Found existing installation: pip 8.1.1
    Not uninstalling pip at /usr/lib/python3/dist-packages, outside environment /usr
Successfully installed pip-18.0

apparently it leaves both versions installed.

does anyone have the direct path to the tarball (not a page with a link as that seems to not show up, right)?
