Updated do fedora 41 today and found this same problem and found how to solve it at least in my case,here is for those of you who may run into it. The problem was a nonexistent repo. I added geogebra repo some years ago, but it looks like it no longer exists. I just erase /etc/yum.repos.d/geogebra.repo and now dnfdragora works as expected. So I think that "AttributeError: 'NoneType' object has no attribute 'installed'" is because the repository no longer exists and there is a None value going in some variable. Need to say this didn't happen in fedora 40.
