Role does not work with Fedora with only dnf5 installed

[tiny-pangolin]

I receive the following output when I import this role on Fedora 40 with only dnf5. The role behaves correctly on Fedora 40 with dnf4 installed

Running sudo dnf5 remove docker docker-common docker-engine executes correctly.

$ sudo dnf5 remove docker docker-common docker-engine
No packages to remove for argument: docker
No packages to remove for argument: docker-common
No packages to remove for argument: docker-engine

I believe this is the task where the failure occurs is Ensure old versions of Docker are not installed in this file tasks/setup-RedHat.yml

I also noticed that the docker_obsolete_packages variable is not used for RedHat. Would it be possible to change the hard coded list to use this variable? Using the variable instead of the hard coded variable would allow me to work around the issue and make the behavior consistent between Debian and RedHat family distros.

[cschindlbeck]

This behavior has been adressed in ansible/ansible#80550 but i think it is only included in 2.18

As for your second suggestion, yes, you can replace the hardcoded list, see here #474

[cschindlbeck]

Upgrading to ansible-core 2.18 does not resolve this unfortunately

is there a reason you closed your PR, and would it possible for me to reopen it?

Yes, it didn't pass the ci, once it is working, we can reopen it for sure, but feel free to fork my branch and fix/improve it
