@adamperkowski 27ac253 please revert this commit if dnf is removed from fastupdate the wild card will be called. It will exit with no suitable packages manager. The --refresh was seperated as it will be easy to debug when an error occurs. Meaning it will be easier to identify if the error occured during refreshing of the mirrors or when updating the packages.

Yes it was. What I'm saying is you were able to revert it yourself. Sorry, should've asked you in the first place.

I am sorry for the hassle. I am not in my hometown and don't have my laptop with me. I am doing all the stuff with my mobile. That's why I asked you.
