This website contains a much cleaner solution, it leaves pip intact as-well and one can easily switch between 3.5 and 3.6 and then whenever 3.7 is released.

http://ubuntuhandbook.org/index.php/2017/07/install-python-3-6-1-in-ubuntu-16-04-lts/

A short summary:

sudo apt-get install python python-pip python3 python3-pip
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2

Then

$ pip -V
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)
$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.5/dist-packages (python 3.5)

Then to select python 3.6 run

sudo update-alternatives --config python3

and select '2'. Then

$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)

To update pip select the desired version and

pip3 install --upgrade pip

$ pip3 -V
pip 9.0.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)

Tested on Ubuntu 16.04.

Let s suppose that you have a system running Ubuntu 16 04  16 10  or 17 04  and you want Python 3 6 to be the default Python   If you re using Ubuntu 16 04 LTS  you ll need to use a PPA   sudo add-apt-repository ppa jonathonf python-3 6     only for 16 04 LTS    Then  run the following  this works out-of-the-box on 16 10 and 17 04    sudo apt update sudo apt install python3 6 sudo apt install python3 6-dev sudo apt install python3 6-venv wget https   bootstrap pypa io get-pip py sudo python3 6 get-pip py sudo ln -s  usr bin python3 6  usr local bin python3 sudo ln -s  usr local bin pip  usr local bin pip3    Do this only if you want python3 to be the default Python   instead of python2  may be dangerous  esp  before 2020     sudo ln -s  usr bin python3 6  usr local bin python   When you have completed all of the above  each of the following shell commands should indicate Python 3 6 1  or a more recent version of Python 3 6    python --version      this will reflect your choice  see above  python3 --version   head -1  which pip    tail -c  3  --version   head -1  which pip3    tail -c  3  --version

In at least in ubuntu 16 10  the default python3 is python3 5   As such  all of the python3-X packages will be installed for python3 5 and not for python3 6   You can verify this by checking the shebang of pip3     head -n1   which pip3     usr bin python3   Fortunately  the pip installed by the python3-pip package is installed into the  shared   usr lib python3 dist-packages such that python3 6 can also take advantage of it   You can install packages for python3 6 by doing   python3 6 -m pip install       For example     python3 6 -m pip install requests   python3 6 -c  import requests  print requests   file      usr local lib python3 6 dist-packages requests   init   py

This answer assumes that you have python3 6 installed  For python3 7  replace 3 6 with 3 7  For python3 8  replace 3 6 with 3 8  but it may also first require the python3 8-distutils package   Installation with sudo  With regard to installing pip  using curl  instead of wget  avoids writing the file to disk   curl https   bootstrap pypa io get-pip py   sudo -H python3 6   The -H flag is evidently necessary with sudo in order to prevent errors such as the following when installing pip for an updated python interpreter      The directory   home someuser  cache pip http  or its parent directory   is not owned by the current user and the cache has been disabled    Please check the permissions and owner of that directory  If executing   pip with sudo  you may want sudo s -H flag       The directory     home someuser  cache pip  or its parent directory is not owned by the   current user and caching wheels has been disabled  check the   permissions and owner of that directory  If executing pip with sudo    you may want sudo s -H flag    Installation without sudo  curl https   bootstrap pypa io get-pip py   python3 6 - --user   This may sometimes give a warning such as      WARNING  The script wheel is installed in   home ubuntu  local bin    which is not on PATH    Consider adding this directory to PATH or  if   you prefer to suppress this warning  use --no-warn-script-location    Verification  After this  pip  pip3  and pip3 6 can all be expected to point to the same target      pip -V  amp  amp  pip3 -V  amp  amp  pip3 6 -V    uniq pip 18 0 from  usr local lib python3 6 dist-packages  python 3 6    Of course you can alternatively use python3 6 -m pip as well     python3 6 -m pip -V pip 18 0 from  usr local lib python3 6 dist-packages  python 3 6
