Enterprise-grade security trusted by millions of users worldwide.
Built for teams that need broader repository access, priority support, and more operational visibility.
Perceived deficiencies of YUM that DNF addresses include poor performance, high memory usage, and the slowness of its iterative dependency resolution. DNF uses libsolv, an external dependency resolver developed by openSUSE.
For a normal user, DNF provides package download, install, update, downgrade, and delete.
One of the most efficient features of DNF is the ability to download only the "differences" between an old and new package (Delta RPMs), which drastically minimizes bandwidth usage during updates.
All RPM packages are digitally signed. The system will refuse to install a package if the signature doesn't match the trusted key, preventing the installation of malicious software.
