DNF5 Install Command Guide for Fedora Linux

DNF5, Fedora’s advanced package manager, simplifies the installation of software with improved performance and powerful features. Whether you’re installing single packages, multiple tools, or managing package groups, DNF5 makes the process efficient and user-friendly.

This guide focuses on the dnf5 install command, offering practical examples and advanced options to help you install and manage software on Fedora with ease.

Preparation Steps

Before using DNF5 to install software, follow these steps to prepare your system:

Verify Your Fedora Version

Ensure you’re running Fedora 41 or later, as DNF5 is included by default starting with this release. To check your version, use:

cat /etc/os-release

Update Your System

Updating your system ensures you have the latest package definitions and avoids potential conflicts. Run:

sudo dnf5 update --refresh

Check Your Internet Connection

Make sure your system is connected to the internet, as DNF5 requires online access to fetch packages from Fedora’s repositories.

These steps ensure your system is ready for installing software using DNF5.

Installing a Single Package

The dnf5 install command is the most straightforward way to install software on Fedora. It resolves dependencies automatically, ensuring all necessary components are installed.

Install a Package

To install a single package, use the following command:

sudo dnf5 install <package_name>

For example, to install the Vim editor, run:

sudo dnf5 install vim

This command fetches Vim and its dependencies from the Fedora repositories and installs them on your system.

Troubleshooting: If you encounter errors, ensure your repositories are updated (as shown in the preparation steps) or check for connectivity issues.

Installing Multiple Packages

The dnf5 install command also allows you to install multiple packages in a single operation, saving time and effort. This is especially useful when setting up a system with several essential tools.

Install Multiple Packages

To install multiple packages at once, list their names separated by spaces:

sudo dnf5 install <package1> <package2> <package3>

For example, to install Vim, Nano, and Htop together, run:

sudo dnf5 install vim nano htop

This command retrieves all three packages and their dependencies from the Fedora repositories, installing them on your system in one transaction.

Advanced Tip

If a dependency issue arises, you can use the --skip-broken option to bypass problematic packages and continue with the installation:

dnf5 install vim nano htop --skip-broken

This ensures the installation of available packages while skipping those that may cause conflicts or errors.

Searching for Packages

Finding the right package is easy with the dnf5 search command. This allows you to locate packages based on keywords in their names or descriptions.

Search for a Package

To search for a package, use the following command:

sudo dnf5 search <keyword>

For example, to find text editors, you can run:

sudo dnf5 search editor

This command searches the Fedora repositories for packages with “editor” in their name or description, providing a list of relevant options.

Advanced Tip

Use more specific keywords for precise results. For instance, searching for “text editor” may yield fewer but more relevant results than just “editor.”

Searching for packages helps you explore available software, ensuring you install the tools best suited to your needs.

Viewing Package Information

The dnf5 info command provides detailed information about a specific package, including its version, repository, and description. This is helpful for verifying package details before installation.

Check Package Details

To view information about a package, use the following command:

sudo dnf5 info <package_name>

For example, to get details about the Vim editor, run:

sudo dnf5 info vim

This command displays:

• Name: The package’s identifier.
• Version: The current version available in the repository.
• Repository: The source repository providing the package.
• Description: A brief overview of the package’s purpose.

Why This is Useful

Verifying package details helps ensure you install the correct software, especially when multiple packages have similar names or functions.

Removing Packages

If you no longer need a package, the dnf5 remove command makes it easy to uninstall it from your system. This ensures your system remains clean and free of unused software.

Remove a Package

To remove a specific package, use the following command:

sudo dnf5 remove <package_name>

For example, to remove the Nano text editor, run:

sudo dnf5 remove nano

This command uninstalls the specified package while keeping the rest of your system intact.

Best Practice: Cleaning Up Dependencies

Unused dependencies can accumulate over time. To remove a package along with any dependencies no longer required, use the --autoremove option:

dnf5 remove nano --autoremove

This not only removes Nano but also clears out orphaned packages, keeping your system efficient and uncluttered.

Upgrading Installed Packages

Keeping your installed packages up to date is essential for maintaining system security, stability, and access to new features. The dnf5 upgrade command simplifies this process by updating all installed packages on your system.

Upgrade All Packages

To upgrade all packages to their latest versions, use:

dnf5 upgrade

This command fetches and installs the latest updates available for your software.

Security Updates Only

To apply only security-related updates, use the --security option:

dnf5 upgrade --security

This ensures that critical vulnerabilities are patched without making other changes to your system.

Why Regular Upgrades Matter

Upgrading installed packages ensures your system is running the latest versions, minimizing bugs and security risks while improving performance.

Advanced Installation Options

DNF5 offers advanced options to customize how packages are installed, making it a versatile tool for managing software on Fedora. These options can help resolve conflicts, handle unavailable packages, and manage updates with greater precision.

Common Advanced Options

• --allowerasing: Resolves dependency conflicts by allowing conflicting packages to be removed.
• --skip-unavailable: Skips over packages that are unavailable during the installation process.
• --offline: Prepares the installation for later execution without requiring an immediate network connection.
• --advisories=<advisory>: Installs packages related to a specific advisory.

Example: Resolving Conflicts

To install Vim while resolving dependency conflicts, use:

dnf5 install vim --allowerasing --advisories=FEDORA-2022-07aa56297a

Example: Offline Installation

To prepare an installation for execution later, use the --offline option:

sudo dnf5 install vim --offline

These advanced options offer flexibility and ensure smooth installation processes, even in complex scenarios.

Managing Package Groups

DNF5 simplifies the management of related software collections through package groups. These groups are curated sets of packages designed for specific tasks, such as development environments or desktop configurations.

Listing Available Groups

To see a list of all available groups, use:

sudo dnf5 group list

This command displays categorized groups, helping you identify which collections suit your needs.

Viewing Group Details

To view detailed information about a specific group, including its description and included packages, run:

sudo dnf5 group info "<group-name>"

For example, to learn about the “Development Tools” group:

sudo dnf5 group info "Development Tools"

Installing a Group

To install a package group and its mandatory packages, use:

sudo dnf5 group install "<group-name>"

For example, to install the “Development Tools” group:

sudo dnf5 group install "Development Tools"

Group installation streamlines the setup process by installing all necessary tools for specific tasks.

Removing Package Groups

If you no longer need a package group, DNF5 allows you to remove the group and its associated packages. This helps keep your system clean and free of unnecessary software.

Remove a Package Group

To remove a group along with all its packages, use:

sudo dnf5 group remove "<group-name>"

For example, to remove the “Development Tools” group, run:

sudo dnf5 group remove "Development Tools"

Retain Installed Packages

If you want to remove the group definition but keep the installed packages, use the --no-packages option:

sudo dnf5 group remove "<group-name>" --no-packages

This option is useful if the group is no longer needed for management purposes but some of its packages are still in use.

Why Remove Groups?

Removing unused groups and their dependencies frees up disk space and ensures your system remains streamlined.

Checking for Obsolete Packages

Over time, unused or outdated packages can accumulate on your system, consuming disk space and potentially causing conflicts. The dnf5 autoremove command identifies and removes these obsolete packages.

Remove Obsolete Packages

To clean up unused dependencies and orphaned packages, use:

dnf5 autoremove

This command scans your system for packages no longer required and safely removes them. It’s a quick way to keep your system lean and efficient.

Why This is Important

Regularly running dnf5 autoremove prevents unnecessary clutter and ensures your Fedora system runs smoothly with only the software you need.

Cleaning the Cache

DNF5 caches metadata and downloaded packages to improve performance during installations and updates. Over time, this cache can accumulate and consume disk space. The dnf5 clean command helps free up this space by removing unnecessary files.

Clean All Cached Data

To clear all cached data, use:

dnf5 clean all

This command removes metadata, package files, and temporary data stored in the cache, freeing up disk space.

Why Clean the Cache?

Clearing the cache is useful when:

• You’re running low on disk space.
• You want to refresh outdated metadata.
• You encounter issues caused by corrupted or incomplete downloads.

Regularly cleaning the cache ensures your system remains clutter-free and avoids potential repository errors.
