Using the DNF software package manager
DNF is a software package manager that installs, updates, and removes packages on Fedora and is the successor to YUM (Yellow-Dog Updater Modified).

DNF has replaced YUM as the default package manager for Fedora since version 22. However, for earlier versions of Fedora, starting from version 18, DNF can be installed from the command-line with:
# yum install dnf
dnf can be used exactly as
yum to search, install or remove packages.
To search the repositories for a package type:
# sudo dnf search packagename
To install the package:
# dnf install packagename
To remove a package:
# dnf remove packagename

autoremove- removes packages installed as dependencies that are no longer required by currently installed programs.
check-update- checks for updates, but does not download or install the packages.
downgrade- reverts to the previous version of a package.
info- provides basic information about the package including name, version, release, and description.
reinstall- reinstalls the currently installed package.
update/upgrade- checks the repositories for newer packages and updates them.
