my question was based on experience but is closed under another reason:
Closed. This question is opinion-based. It is not currently accepting answers.
Your question asks, "Isn't Fedora's DNF a failure?".
A quote from What types of questions should I avoid asking?:
To prevent your question from being flagged and possibly removed, avoid asking subjective questions where …
- your question is just a rant in disguise: “______ sucks, am I right?”
Your question is a rant in disguise. The community, therefore, voted to close it.
You do have some content that could be interesting to look further at (some issue with
dnf autoremove?). Still, you provide no information about this that gives us any handle on the issue, like error messages, configuration details etc.
Your general sense of
dnf being "slow" could also be presented more objectively and later possibly properly debugged. However, there is no information to go on in the question.
The question as a whole is opinion-based, and when disregarding the rant, it is unclear (lacking enough details) and unfocused (more than a single issue).
Since the question has accumulated several downvotes, I would suggest asking new and separate questions about your issues with
dnf if you want help resolving them.
