Hi Fabiano,

Sorry you are running into this issue.

Unfortunately, the installer as it is written now, requires RHEL 8.2. Because RHEL 8.2 provides that module:

However, we probably can make it work. Because it appears that you got your Python 3.8 from an external source.

We can probably fix this with 2 steps:

  1. You removing that task “Enable Python 3.8 module stream” from (~.ansible/collections/ansible_collections/pulp/pulp_installer/roles/pulp_common/tasks/install.yml ).

  2. Set the Ansible variable pulp_python_interpreter to the path to your python 3.8 binary named “python3.8”.

You can find it by running:
$ which python3.8

(No need to set it if it is at /usr/bin/python3.8).

Let me know if that works. If it does, I can prescribe a proper fix for the installer.

Hello Mike,
I have upgraded my RHEL from 8.1 to 8.2 and looks like it worked however I’m facing this issue right now.
If I set up the code “no_log: true” to “no_log:false”, also doesn’t work.
Do you have any suggestion?

It looks like the pulpcore worker services are either not starting, or failing to stay running.

Could you run this command?
$ sudo systemctl status --full pulpcore-worker@1.service
