Fedora 30 : How to remove packages without dependency.

In this tutorial, I will show you how to remove packages without dependency.
I have this software named freecad.x86_64 and I want to remove it.
If I use the dnf tool then I got this output:

[root@desk mythcat]# dnf remove freecad.x86_64 
Dependencies resolved.

The package is from Nightly FreeCAD, you can enable it if you want to install later:

[root@desk mythcat]# sudo dnf copr enable @freecad/nightly

To solve this issue you need to change this file:

[root@desk mythcat]# vim /etc/dnf/dnf.conf

From clean_requirements_on_remove=True to clean_requirements_on_remove=False.
The next commands will fix and remove the package:

[root@desk mythcat]# dnf clean all
86 files removed
[root@desk mythcat]# dnf remove freecad.x86_64
