    Trying to update packages using DNF module:

    - name: update all RPM packages using dnf
      dnf:
        name: '*'
        state: latest

    Got the following error:

    fatal: [server]: FAILED! => {"changed": false, "cmd": "dnf install -y python3-dnf", "msg": "Could not import the dnf python module using /opt/freeware/bin/python3 (3.7.10 (default, May 13 2021, 04:50:00) [GCC 8.3.0]).

    Could not import the dnf python module using /opt/freeware/bin/python

    python3-dnf is installed, that's why it says "Nothing to do":

    # rpm -qa | grep 3-libdnf
    python3-libdnf-0.39.1-1.ppc

    looks like the cause for the error is the following line in ansible.cfg:

    interpreter_python = /opt/freeware/bin/python3

    If the line is changed to python3_32 (32 bit version of python3), everything works ok:

    interpreter_python = /opt/freeware/bin/python3_32

    Hi Andrey,

    Yes dnf modules are 32bit right now hence it would be used with 32bit python. 
    The reason for that is rpm and its library are 32bit in AIX.
    For future release of AIX we will look for 64bit solution but for AIX 7.1 and 7.2 this is going to be the case. Where ansible dnf module will have to use 32bit python3.

    hi,

    Any update on this topic ?

    Just tested on an AIX 7.2 LPAR with all RPMs up-to-date and we still have that issue on AIX 7.2. Changing python interpreter for that task to /opt/freeware/libexec/python3.9_32 is the only workaround we found for now

    Thanks and best regards
    Lionel

    As clearly mentioned above, rpm & its libraries are 32bit in AIX 7.1 and & AIX 7.2 , and hence the 32bit dnf. So the interpreter has to be 32bit which is "/opt/freeware/libexec/python3.9_32"
