In the above example, we can see both "Installed Packages" and "Available Packages". Further detailed information of a package can be viewed with the ‘info’ argument. Note that after confirming the packages that will be installed, you will be asked to provide input. The "dnf remove" command is used to remove a specified package. This can be done by disabling the repository with --disablerepo. Packages that are related to each other may be grouped together into a package group. Install DNF. (Please note, if the group package contains spaces within its name, then you must place single quotes around the group name.). The command "dnf grouplist" can be used to display available groups on your system. To update this package, we use the "dnf update" command: Basic Syntax: dnf downgrade package name Those are the files which DNF uses to determine the remote availability of packages. As you may know, the Fedora Linux operating system is essentially a bleeding edge testing ground for packages that may be included in RHEL/CentOS based distributions in the future. This option is useful if you do not know the full name of the package. Basic Syntax: dnf reinstall package name I'm not running Rawhide mind you, but F23 only includes 5.9-21 in the standard fedora repo. Like Yum, DNF is quite powerful as it’s capable of automatically resolving dependency issues, and is similar to other package managers such as ‘apt-get’ in Debian based distributions. Below are some examples of the "dnf help" command in use. Packages can be uninstalled with the ‘remove’ argument, as shown below. This speeds up dnf so that it doesn’t have to keep querying this information from the Internet. The "dnf check-update" command is used to check for available updates on your Linux system. The fact is that you are not requesting the same repositories, if you don't use the same --disablerepo options. dnf clean all NOTE - You can use these HTML tags and attributes:

. Basic Syntax: dnf update As you have seen in the above examples, the dnf command can provide quite a bit of output. We can specify a new repository by manually editing or creating a new .repo file in the /etc/yum.repos.d directory, however we can much more easily create a persistent repository with the ‘dnf config-manager’ command. This forces DNF to regenerate the cache files the next time it is run. In the following example, we will downgrade the previously updated package "zip.x86_64". Basic Syntax: dnf clean option The above command is used to display the currently installed version of DNF. It’s also worth noting that package installations, updates, or removals are also logged in the /var/log/dnf.log file, here’s an example of what’s logged here. Install dnf packages from specific repository How can I install dnf packages from a specific repository (fedora-rawhide in this case). Note that we do not have to run check-update prior to this. .FIYolDqalszTnjjNfThfT{max-width:256px;white-space:normal;text-align:center} Now we can download the RPM file to the local system. ;(2) Since dnf does not give info on where it installed, what is the best way to find that location? Basic Syntax: dnf provides provide-spec This can also be used against a file on the file system to check which package provides that file. .s5ap8yh1b4ZfwxvHizW3f{color:var(--newCommunityTheme-metaText);padding-top:5px}.s5ap8yh1b4ZfwxvHizW3f._19JhaP1slDQqu2XgT3vVS0{color:#ea0027} Press question mark to learn the rest of the keyboard shortcuts. A community for users, developers and people interested in the Fedora Project and news and information about it. As of Fedora 22, it has become the default package manager. Here we can see the “Basic Web Server” group is actually made up of three other groups, Base, Core, and Web Server. This is quite similar, except that we replace ‘installed’ with ‘available’ to instead list all available packages. This is similar to performing a ‘dnf remove’ followed by a ‘dnf install’, however here it’s done in the one command and custom configuration is not removed, as a ‘dnf remove’ will delete all configuration files managed by the package.
