That’s odd, maybe one that we missed. You can use --reset-foreman-plugin-default-hostgroup-hostgroups as an argument. That should reset it to the default value.

Before your reply I started a run with --no-enable-foreman-plugin-default-hostgroup
The upgrade failed because of pulp running.
I re-ran the upgrade with
–reset-foreman-plugin-default-hostgroup-hostgroups and it seems to have worked.

if I try running foreman-installer --enable-foreman-plugin-default-hostgroup
I get the error message even after --reset-foreman-plugin-default-hostgroup-hostgroups

Looking at the code, you may have hit a bug in our parser: Bug #31565: Validation of array's as static parameters on a class is incorrectly handled - Kafo - Foreman

I think the workaround is to modify your answers file manually. If you already have the RPM package installed, you don’t really need to though. The installer can’t remove the plugin so what --no-enable-foreman-plugin-default-hostgroup technically does is roughly “stop making sure the plugin is installed”.

How would I modify the answers file?

I am hitting the similar issue. In my case, I want the plugin to be installed via the foreman-installer and use the configuration value from the custom.yaml file.
Is that possible? What steps do I need to take?

@ekohl Do you have a suggestion to overcome the issue?

Sadly I did not find a solution.
I have that feature disabled and expect at some point I may just end up doing a clean re-install.
