Originally assigned to: @jhollowe on GitHub.

I have an Ansible playbook that use a Role that uses modules based off the community.general proxmox module, except that they use the openssh backend. This works fine with Python 3.12.x but now fails with Python 3.13.x with the error Chosen backend requires 'openssh_wrapper' module.

This message is coming from proxmoxer when it checks to see if the openssh_wrapper module is installed and for some reason it fails even when the module is there.

Example of the playbook running:

(venv129) cloudcodger/showcase % python3 --version
Python 3.12.9
(venv129) cloudcodger/showcase % ansible-playbook test_pve.yml

PLAY [Configure the Proxmox Datacenter.] ***************************************************************************************************

TASK [Test calling openssh module.] ********************************************************************************************************
ok: [localhost]

PLAY RECAP *********************************************************************************************************************************
localhost                  : ok=1    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

Example of the playbook run with the error:

(venv132) cloudcodger/showcase % python3 --version
Python 3.13.2
(venv132) cloudcodger/showcase % ansible-playbook test_pve.yml

PLAY [Configure the Proxmox Datacenter.] ***************************************************************************************************

TASK [Test calling openssh module.] ********************************************************************************************************
fatal: [localhost]: FAILED! => {"changed": false, "module_stderr": "Chosen backend requires 'openssh_wrapper' module\n\n", "module_stdout": "", "msg": "MODULE FAILURE: No start of json char found\nSee stdout/stderr for the exact error", "rc": 1}

PLAY RECAP *********************************************************************************************************************************
localhost                  : ok=0    changed=0    unreachable=0    failed=1    skipped=0    rescued=0    ignored=0

In both cases, using proxmoxer module version 2.2.0.

Here is the test_pve.yml playbook that is failing with Python 3.13.

---
- name: Configure the Proxmox Datacenter.
  gather_facts: false
  hosts: localhost

  tasks:
    - name: Test calling openssh module.

@jhollowe commented on GitHub (Feb 18, 2025):

I was working on trying to get py3.13 working, but it looks like 3.13 deprecated something that the openssh-wrapper library was using. Since that library hasn't been updated in many years and has not accepted previous PRs, I just forked it and added a fix for this issue.

Feel free to use git+https://github.com/proxmoxer/openssh-wrapper.git@master in your requirements.txt (or however else you are installing python libraries). I need to reach out to the current maintainers of openssh-wrapper and see if they want to continue owning it or would like this org to take it over.
