如何在Raspbian上安装Ansible？

Question

I would like to install Ansible on my Raspberry Pi (raspbian/jessie) so that I can maintain it. Unfortunately, I don't seem to be able to install it. I've tried APT and PIP so far but each has a hurdle.

APT

pi@retropie:~ $ sudo apt-add-repository ppa:ansible/ansible

Traceback (most recent call last):
  File "/usr/bin/apt-add-repository", line 167, in <module>
    sp = SoftwareProperties(options=options)
  File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 105, in __init__
    self.reload_sourceslist()
  File "/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", line 595, in reload_sourceslist
    self.distro.get_sources(self.sourceslist)

    (self.id, self.codename))
aptsources.distro.NoDistroTemplateException: Error: could not find a distribution template for Raspbian/jessie

PIP (Python 2.7.9, pip 1.5.6)

pi@retropie:~ $ sudo pip install ansible

Python 3

As you can see from the above error, "cryptography" indicates it needs > python3 I looked at the installation requirements and found that you need python 3.5+ if you use 3. Rasbian comes with 3.4...

I then tried to get python 3.6 installed using a couple of ppa's (ppa:jonathonf/python-3.6 and ppa:deadsnakes/ppa) but there aren't distros available for raspbian/jessie either.

After that I started looking at pulling down and compiling python from source but I'm expecting I'll hit another hurdle.

Ugh...

In summary, does anyone have any ideas how I can get Ansible installed on a Raspberry Pi?

Answer 1

Slightly old question but its the first result that comes up when googling for how to install Ansible on Raspbian so thought I'd update it. If you're running stretch (or stretch-lite)

You can just do

sudo apt-get install ansible

However currently the version of Ansbile in the Raspbian repositories is 2.2 which is a little old

Following instructions (with a little modification to overcome some errors) from the Ansible installation page you can do the following:

First run

sudo apt-get install dirmngr

Edit your /etc/apt/sources.list and append

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

then run

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

This will give you version 2.7.8 as of today.

Edited to include missing command (thanks SpacePope) and correct formatting.

Answer 2

Jessie was released in 2015 and is officially obsolete. Stretch is the current Raspbian repo, and it has python3.5 without adding PPAs.

You can then simply install Ansible with pip3.
