How to Install Python 3.6.1 in Ubuntu 16.04 LTS

This quick tutorial is going to show you how to install the latest Python 3.6.1 in Ubuntu 16.04 LTS via PPA.

Ubuntu 16.04 comes with both Python 2.7 and Python 3.5 by default. You can install Python 3.6 along with them via a third-party PPA by doing following steps:

1. Open terminal via Ctrl+Alt+T or searching for “Terminal” from app launcher. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:jonathonf/python-3.6

Type in your password (no visual feedback due to security reason) when it asks and hit Enter.

2. Then check updates and install Python 3.6 via commands:

sudo apt-get update

sudo apt-get install python3.6

Now you have three Python versions, use python command for version 2.7, python3 for version 3.5, and/or python3.6 for version 3.6.1.

3. To make python3 use the new installed python 3.6 instead of the default 3.5 release, run following 2 commands:

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

Finally switch between the two python versions for python3 via command:

sudo update-alternatives --config python3

After selecting version 3.6:

python3 -V

UPDATE: due to this bug, gnome-terminal won’t launch after step 3, a workaround is running following commands to recreate the symlink:

sudo rm /usr/bin/python3

sudo ln -s python3.5 /usr/bin/python3

  1. I tried it and it works fine, but I was not able to correctly install python3-dev module, which then prevents to install some other modules.

  2. After following above procedures i went to install my own selection as follows:

    apt-get install python3.6 idle-python3.6 python3.6-doc python3.6-examples libpython3.6 libpython3.6-stdlib python-clang-3.6 python-lldb-3.6 libpython3.6-dbg python3.6-venv

    no error after the above command above.

    Linux ubuntu-net 4.4.0-93-generic #116-Ubuntu SMP Fri Aug 11 21:17:51 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

    to make python3.6 as the default, remove the rest of pythons and create a soft link to the python3.6:

    ls /usr/bin/python*
    /usr/bin/python /usr/bin/python2.7 /usr/bin/python3.5 /usr/bin/python3.6 /usr/bin/python3m
    /usr/bin/python2 /usr/bin/python3 /usr/bin/python3.5m /usr/bin/python3.6m

    rm /usr/bin/python
    ln -s /usr/bin/python3.6 /usr/bin/python
    ln -s /usr/bin/python3.6m /usr/bin/pythonm
