    Hi All,

    I keep on having this error when I try to run the sample playbook I am testing on my switch. I am pretty new using Ansible for Aruba (though I understand at least how Ansible works).


    fatal: [aoscx_1]: FAILED! => {

    I followed the instruction on how to setup the aruba modules from this website, Getting Started with Ansible and AOS-CX

    but for some reason, I'm getting this error message. My ansible version is 2.11 (core),  python 3.6.x, CentOS7. Hope someone can point me what am I missing. 

    Many thanks!

    Hello!

    Although you may have python 3 installed it appears your Ansible is using your python2 based on this output:
    invoke_module(zipped_mod, temp_path, ANSIBALLZ_PARAMS)\n  File \"/home/administrator/.ansible/tmp/ansible-local-1512yoz5g5cy/ansible-tmp-1635749575.7712095-1524-155447344171476/AnsiballZ_aoscx_vlan.py\", line 41, in invoke_module\n    run_name='__main__', alter_sys=True)\n  File \"/usr/lib64/python2.7/runpy.py\", line 176, in run_module\n    fname, loader, pkg_name)\n  File \"/usr/lib64/python2.7/runpy.py\", line 82, in _run_module_code\n    mod_name, mod_fname, mod_loader, pkg_name)\n  File \"/usr/lib64/python2.7/runpy.py\", line 72, in _run_code\n    exec code in run_globals\n  File


    Please ensure you have `pyaoscx` installed via python 3 and you should be able to set the python interpreter to whichever path python 3 is installed in your system. Here are some guides to help you:
    https://developer.arubanetworks.com/aruba-aoscx/docs/getting-started-with-ansible-and-aos-cx

    Here's an example of doing it in the playbook:
    - hosts: all
      collections:
        - arubanetworks.aoscx
      vars:
        ansible_python_interpreter: /usr/bin/python3    
      gather_facts: False
      tasks:
        - name: Create VLAN 300 with description and name
          aoscx_vlan:
            vlan_id: 300
            name: UPLINK_VLAN
            description: This is VLAN 300

    Hi Tiffany,

    Thanks for the reply. I set it to user python3 but still have the same result which is weird.  The pyaoscx is also installed. I run again the setup as per guide but I've got the same output. Should I just recreate the whole  control node?

    ***** Update ******

    I created a new control node running on Ubuntu instead (though OS shouldn't be an issue at all)  and did a fresh install and seems to work but what I notice is that when I run the same sample playbook (VLAN creation), it keeps on applying the same changes which is not a normal behaviour. I might open a new thread about this I guess.

    Are you using a virtual environment?

    Can you try executing this command?
    python3 -m pip install -r https://raw.githubusercontent.com/aruba/aoscx-ansible-collection/master/requirements.txt

    Hi Tiffany,

    I tried that too. I guess my control node are in a total mess now so I decided to spin up a new VM instead and did a fresh install and it seems to work fine. I did try @alagoutte's suggestion to remove pyaoscx and that error message was solve but it leads to another issue that is why I setup a new control node for this purpose. 


    Regards.
