    You can rest assured that when you say “You can rest assured” in the future it will not work as you expect it to due mostly to bad assumptions such as in this case (not that it matters but using a headless latest generic installed openmediavault) we need to change the basic commands for the shell version apt/apt-get as assuming there’s a GUI application installed aptitude/yum etc will stop the beginner in their tracks as per all current so called developers not being end user/home user friendly etc…

    so anyway,

    apt -y groupinstall development
    apt -y install zlib-devel
    

    In Debian we will need to install gcc, make, and the zlib compression / decompression library:

    apt-get  -y install gcc make zlib1g-dev
    

    To install Python 3.6, run the following commands:

    wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz
    tar xJf Python-3.6.3.tar.xz
    cd Python-3.6.3
    ./configure
    make -j4
    make install
    

    Now relax and go grab a sandwich because this may take a while. When the installation is complete, use which to verify the location of the main binary:

    # which python3
    # python3 -V
    

    before

    /usr/local/bin/python3
    

    after

    /usr/local/bin/python3
    

    before

    python3 -V
    Python 3.5.3
    

    after

    [email protected]:~/Python-3.6.3# python3 -V
    Python 3.5.3

    Such a great tutorial, thanks

  3. Sixpack Kid says:

    On OpenSUSE, you might need to install readline package as well.

    $ sudo zypper install zlib-devel
    $ sudo zypper install readline-devel
    $ ./configure --enable-optimizations
    $ make
    $ sudo make install

    We finished our work but still, the installation is in progress. What shall I do ??

  5. Alex W. says:

    Mr. Cánepa, thanks for the method which you wrote and that worked perfectly for me.

    Now I have a related and urgent question for you, please.

    After I played with the Python 3.6 interpreter on command line, I think that my Linux Mint 17 does NOT support it very well for convenient use in the terminal.

    So I want to reverse to the system default Python 3.4 . Do you have some idea about how I should do it safely? I’ve googled about that and found no answer.

    Thank you very much.

    Hi,

    After downloading python, when I use this command (./configure), it shows below error.

    configure: error: in /root/Python-3.6.3 :
    configure: error: no acceptable C compiler found in $PATH
    see `config.log` for more details

    Can you please tell me next what should I do?

    • Ravi Saive says:

      @Apurba,

      Install C Compiler (GCC) using the following command as per your Linux distribution (run as root).

      # yum groupinstall "Development tools"  [On RedHat based]
      # apt-get install build-essential       [On Debian based]

      @Rogerio,

      Have you installed necessary development dependencies on the system? If not, please install it as shown in the article, before installing Python from sources..

    how do i uninstall python3.5.2

  9. Diane says:

    I thought that installing 3.6 on Linux without care can wreck your system, my understanding is that Linux uses 2.x for yum. Is this true? Do you have to install it separately from 2.x? If so, how do you do that? Sorry, I’m new to this..

    • Gabriel A. Cánepa says:

      Diane,

      You can rest assured that you won’t wreck your system by following the steps outlined in this article :). And by the way, Python3.x and Python2.x can coexist in the same problem without issues. However, problems may arise if you try to change the symbolic links that point to the binaries — python points to python version 2 whereas python3 points to version 3. Hope this helps.

    Hi,

    An easy way to get precompiled packages is with conda package manager. You can install miniconda: https://conda.io/miniconda.html
    And then create a python 3.6 env in a virtualenv-style:

    conda create -n mypy36_env python=3.6
    source activate mypy36_env
