I’m attempting to install the all-in-one, containerized version of Ansible Automation Platform (AAP) 2.4 on a Red Hat Enterprise Linux (RHEL) 9.5 server, but I’m encountering a persistent error during the initialization of the Automation Hub database. The installation fails with a `ModuleNotFoundError` for the `galaxy_ng.app.auth.session.SessionAuthentication` module, preventing the `pulpcore-manager` command from completing. I’ve tried using both the bundled installer and an online installation (pulling images from Red Hat), but the issue persists. I need assistance troubleshooting and resolving this problem to complete the AAP 2.4 deployment. **Error:** ```auto TASK [ansible.containerized_installer.automationhub : Initialize the automation hub database] ******************************************************************************************************************************* task path: /home/ansible/aap_install/ansible-automation-platform-containerized-setup-bundle-2.4-2-x86_64/collections/ansible_collections/ansible/containerized_installer/roles/automationhub/tasks/containers.yml:98 <192.168.2.5> ESTABLISH LOCAL CONNECTION FOR USER: ansible <192.168.2.5> EXEC /bin/sh -c 'echo ~ansible && sleep 0' <192.168.2.5> EXEC /bin/sh -c '( umask 77 && mkdir -p "` echo /home/ansible/.ansible/tmp `"&& mkdir "` echo /home/ansible/.ansible/tmp/ansible-tmp-1740776455.0262334-276731-98536928879768 `" && echo ansible-tmp-1740776455.0262334-276731-98536928879768="` echo /home/ansible/.ansible/tmp/ansible-tmp-1740776455.0262334-276731-98536928879768 `" ) && sleep 0' Using module file /home/ansible/aap_install/ansible-automation-platform-containerized-setup-bundle-2.4-2-x86_64/collections/ansible_collections/containers/podman/plugins/modules/podman_container.py <192.168.2.5> PUT /home/ansible/.ansible/tmp/ansible-local-269481ruy6s972/tmpdhky2pv_ TO /home/ansible/.ansible/tmp/ansible-tmp-1740776455.0262334-276731-98536928879768/AnsiballZ_podman_container.py <192.168.2.5> EXEC /bin/sh -c 'chmod u+x /home/ansible/.ansible/tmp/ansible-tmp-1740776455.0262334-276731-98536928879768/ /home/ansible/.ansible/tmp/ansible-tmp-1740776455.0262334-276731-98536928879768/AnsiballZ_podman_container.py && sleep 0' <192.168.2.5> EXEC /bin/sh -c '/usr/bin/python3 /home/ansible/.ansible/tmp/ansible-tmp-1740776455.0262334-276731-98536928879768/AnsiballZ_podman_container.py && sleep 0' <192.168.2.5> EXEC /bin/sh -c 'rm -f -r /home/ansible/.ansible/tmp/ansible-tmp-1740776455.0262334-276731-98536928879768/ > /dev/null 2>&1 && sleep 0' "Traceback (most recent call last):", " File \"/usr/lib/python3.9/site-packages/rest_framework/settings.py\", line 177, in import_from_string", " return import_string(val)", " File \"/usr/lib/python3.9/site-packages/django/utils/module_loading.py\", line 17, in import_string", " module = import_module(module_path)", " File \"/usr/lib64/python3.9/importlib/ __init__.py\", line 127, in import_module", " return _bootstrap._gcd_import(name[level:], package, level)", " File \"\", line 1030, in _gcd_import", " File \"\", line 1007, in _find_and_load", " File \"\", line 984, in _find_and_load_unlocked", "ModuleNotFoundError: No module named 'galaxy_ng.app.auth.session'", "", "During handling of the above exception, another exception occurred:", "", "Traceback (most recent call last):", " File \"/usr/bin/pulpcore-manager\", line 33, in ", " sys.exit(load_entry_point('pulpcore==3.23.20', 'console_scripts', 'pulpcore-manager')())", " File \"/usr/lib/python3.9/site-packages/pulpcore/app/manage.py\", line 11, in manage", " execute_from_command_line(sys.argv)", " File \"/usr/lib/python3.9/site-packages/django/core/management/ __init__.py\", line 419, in execute_from_command_line", " utility.execute()", " File \"/usr/lib/python3.9/site-packages/django/core/management/ __init__.py\", line 395, in execute", " django.setup()", " File \"/usr/lib/python3.9/site-packages/django/ __init__.py\", line 24, in setup", " apps.populate(settings.INSTALLED_APPS)", " File \"/usr/lib/python3.9/site-packages/django/apps/registry.py\", line 122, in populate", " app_config.ready()", " File \"/usr/lib/python3.9/site-packages/pulpcore/app/apps.py\", line 244, in ready", " super().ready()", " File \"/usr/lib/python3.9/site-packages/pulpcore/app/apps.py\", line 122, in ready", " self.import_viewsets()", " File \"/usr/lib/python3.9/site-packages/pulpcore/app/apps.py\", line 159, in import_viewsets", " from pulpcore.app.viewsets import NamedModelViewSet", " File \"/usr/lib/python3.9/site-packages/pulpcore/app/viewsets/ __init__.py\", line 1, in ", " from .base import ( #
