Speed up DNF DNF is very slow without modifying dnf.conf. We’ll modify /etc/dnf/dnf.conf for speed up DNF. Dependencies deltarpm DNF.conf Add these to /etc/dnf/dnf.conf: # dnf.conf fastestmirror=true max_parallel_downloads=20 deltarpm=true By the way, you can add defaultyes=true for [Y/n] (default is [y/N]) in package installs.
