python_pip fails on Debian 10

[pierre-b]

Hi Robert,

I get this error while using the python_pip role on a fresh Debian:

Playbook

---
- name: Prepare
  hosts: all
  gather_facts: no
  become: yes

  roles:
    - role: robertdebock.bootstrap
    - role: robertdebock.buildtools
    - role: robertdebock.python_pip

Output

TASK [robertdebock.python_pip : update pip] ************************************************************************
FAILED - RETRYING: update pip (3 retries left).
FAILED - RETRYING: update pip (2 retries left).
FAILED - RETRYING: update pip (1 retries left).
fatal: [51.91.148.106]: FAILED! => {"attempts": 3, "changed": false, "msg": "Unable to find any of pip2, pip to use. pip needs to be installed."}

Environment

• Control node OS: MacOS
• Control node Ansible version: 2.9.6
• Managed node OS: Debian 10

Thanks for your help

It's indeed not tested, I'll try to add support for it.

Thanks for your input!

[robertdebock]

Local testing worked, let's wait CI results.

[pierre-b]

Thanks for this quick fix!

[robertdebock]

I added CI tests for Debian bullseye (I think it's version 10) and they are working

I did do a lot of changes, but not specifically to the logic.

Just released version 3.3.0 of this role. Can you have a look if that works for you?

Regards,

Robert de Bock.

I'm having the same problem on ubuntu 18.04, fresh off of ansible-galaxy

I had to run apt install python-pip for the role to run, but that defeats the purpose.

Hi @robertdebock , finally took time to retry this, I still have the same error.
What I want to achieve is installing Zabbix with this playbook :

---
- name: Prepare
  hosts: all
  gather_facts: yes
  become: yes

  roles:
    - role: robertdebock.bootstrap
    - role: robertdebock.buildtools
    # - role: robertdebock.python_pip
      # python_pip_modules: 
      #   - name: PyMySQL
    - role: robertdebock.container_docs
    - role: robertdebock.mysql
      mysql_databases:
        - name: zabbix
          encoding: utf8
          collation: utf8_bin
      mysql_users:
        - name: zabbix
          password: zabbix
          priv: "zabbix.*:ALL"
    - role: robertdebock.zabbix_repository
    - role: robertdebock.zabbix_server

But I got the following error:
TASK [robertdebock.mysql : create databases] *********************************************************************** failed: [51.91.148.106] (item=zabbix) => {"ansible_loop_var": "item", "changed": false, "item": {"collation": "utf8_bin", "encoding": "utf8", "name": "zabbix"}, "msg": "The PyMySQL (Python 2.7 and Python 3.X) or MySQL-python (Python 2.X) module is required."}

So I added this role to my playbook after the buildtools:

    - role: robertdebock.python_pip
      python_pip_modules: 
        - name: PyMySQL

Which throws the following error:

TASK [robertdebock.python_pip : update pip] ************************************************************************
FAILED - RETRYING: update pip (3 retries left).
FAILED - RETRYING: update pip (2 retries left).
FAILED - RETRYING: update pip (1 retries left).
fatal: [51.91.148.106]: FAILED! => {"attempts": 3, "changed": false, "msg": "Unable to find any of pip2, pip to use.  pip needs to be installed."}

When I log into the Debian 10 machine pip is not available but pip3 is.

Any idea please?

[pierre-b]

Found out that adding the following var to my hosts solved the python issue, could you please add this to the docs?

[py3-hosts:vars]
ansible_python_interpreter=/usr/bin/python3

[robertdebock]

I think you are using an older version of Ansible that does not support python discovery.

With my debian latest 10/buster container (based on debian:latest) I run image=debian molecule test which succeeds.

This is also tested on GitHub Actions and on Travis CI and succeeds.

TL;DR: Please update your Ansible version to at least 2.8.

[pierre-b]

unfortunately I'm using Ansible 2.9.6... ended up with a manual installation...
