How to install ansible 2.9+ on ubuntu 18.04 and utilize python3? – Debian

I’m trying to install minimal ansible 2.9.x on Ubuntu Bionic (18.04 LTS).

The final goal is to build new disk image (using packer) on every commit and want the process to be as fast as possible.

Using default Ubuntu ansible

Default ansible in bionic is 2.5.x.

This is too old, all ansible scripts are written for 2.9+.

Using official PPA

Using recommended way to install suggests adding following line to /etc/apt/sources.list:

deb http://ppa.launchpad.net/ansible/ansible/ubuntu trusty main

and running following commands:

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 93C4A3FD7BB9C367
$ sudo apt update
$ sudo apt install ansible

but it still requires python2 packages:

$ sudo apt install ansible

Using pip

This is my current approach but installing pip3 and then installing ansible via pip is another extra step:

…which adds unnecessary time to the packer process 🙁

Any hints?

Ubuntu 18.04 comes with python3 already installed and ansible can be easily configured to use python3.
Does anyone know a way how to install ansible 2.9 without the need to install python2 or pip3?

    I’ve had the same problem. In my case was mandatory to be in 2.9.+ because of AWX requirements … If you are in Ubuntu 18.04 you can follow these steps:

    $ sudo apt install software-properties-common
$ sudo apt-add-repository ppa:ansible/ansible
$ sudo apt update

$ sudo apt install ansible

    That’s it.

    $ ansible --version
  |___ ansible 2.9.7

    I hit the same issue. When I used

    sudo apt install ansible

    ansible was installed with Python 2.7.x

    I uninstalled everything and installed ansible using pip. Now, when I do ansible –version I get

    ansible 2.9.11
    config file = /etc/ansible/ansible.cfg
    configured module search path = [‘/root/.ansible/plugins/modules’, ‘/usr/share/ansible/plugins/modules’]
    ansible python module location = /usr/local/lib/python3.6/dist-packages/ansible
    executable location = /usr/local/bin/ansible
    python version = 3.6.9 (default, Apr 18 2020, 01:56:04) [GCC 8.4.0]

    As mentioned on the issue, it is currently recommended for Ubuntu users to use the Debian repository. You can download it directly here, and install the downloaded deb package using

    sudo apt-get install ./ansible_x.y.z_all.deb

    This will install ansible without installing python2.
    I have successfully tested this on Ubuntu 19.10.

    I have recompiled the focal version of ansible (which uses python3) against bionic and published that in my PPA. There were only minimal changes necessary. You can use only the package in question instead of enabling the entire PPA. You will end up with ansible 2.9.6.

    To install Ansible version 2.9 on Ubuntu 18 04:

    Check if you have already a repostory configured:

    deb http://ppa.launchpad.net/ansible/ansible/ubuntu focal main

    This repository above does not install the 2.9 anymore, instead, use:

    deb http://ppa.launchpad.net/ansible/ansible-2.9/ubuntu focal main

    If you do not have any repository of http://ppa.launchpad.net/ansible

    Add a new file to: /etc/apt/sources.list.d/ansible.list

    deb http://ppa.launchpad.net/ansible/ansible-2.9/ubuntu focal main

    Run (Check if the order of the repositories are good)

    sudo apt update

    Install ansible:

    sudo apt install ansible

    Check version:

    ansible --version
