How To Install Viber on Fedora 41

Communicating with friends, family, and colleagues has never been easier thanks to messaging applications like Viber. As a cross-platform VoIP and instant messaging service, Viber allows users to make free calls, send messages, share media, and create group chats across multiple devices. While installing Viber on Windows or macOS might seem straightforward, Linux users often face unique challenges. This comprehensive guide will walk you through various methods to install Viber on Fedora 41, ensuring you can enjoy this powerful communication tool on your Linux system.

What is Viber?

Viber, also known as Rakuten Viber, is a free cross-platform voice over IP (VoIP) and instant messaging application that allows users to communicate with others regardless of their location. Initially launched in 2010, Viber has grown to become one of the most popular messaging platforms worldwide with over a billion users.

The application offers a rich feature set including:

• Free voice and video calls between Viber users
• Text messaging with support for GIFs, stickers, and emoji
• Photo and video sharing capabilities
• Group chats with up to 250 participants
• End-to-end encryption for enhanced security and privacy
• Disappearing messages for sensitive information
• Syncing between mobile and desktop devices

Unlike open-source alternatives, Viber is a closed-source application. However, it provides native executable clients for various Linux distributions, including Fedora. The desktop version integrates seamlessly with the mobile application, allowing you to continue conversations across devices without interruption.

Prerequisites for Installing Viber on Fedora 41

Before proceeding with the installation of Viber on your Fedora 41 system, ensure you meet the following requirements:

• An active internet connection
• Administrative (sudo) privileges on your Fedora system
• Viber application installed and activated on your mobile phone
• Fedora 41 with updated system packages
• Sufficient storage space (approximately 200MB)

Most importantly, you must have Viber installed on your mobile device first. The desktop version of Viber requires synchronization with your mobile account through a QR code scanning process.

To verify your Fedora version, open a terminal and run:

cat /etc/fedora-release

This command should return “Fedora Linux release 41” if you’re running the correct version.

Installation Methods Overview

There are several ways to install Viber on Fedora 41, each with its own advantages and potential challenges. The three primary installation methods are:

1. RPM Package Installation: The traditional method using Fedora’s native package format
2. AppImage Installation: A portable application format that doesn’t require installation
3. Snap Package Installation: Using Snap, a universal package management system

Your choice may depend on factors such as your technical expertise, preference for system integration, and specific requirements. The following sections detail each method comprehensively.

Method 1: Installing Viber RPM Package

The RPM (Red Hat Package Manager) method is the most traditional way to install applications on Fedora systems. This approach integrates Viber directly into your system, making it easily accessible from your application menu.

Downloading the RPM Package

First, you need to download the official Viber RPM package. Open a terminal and use the wget command to download the package:

wget -c https://download.cdn.viber.com/desktop/Linux/viber.rpm

If wget isn’t installed on your system, you can install it using:

sudo dnf install wget

Installing the RPM Package

Once the download is complete, navigate to the directory containing the downloaded file and install it using DNF (Dandified YUM), Fedora’s package manager:

sudo dnf localinstall viber.rpm

Alternatively, you can use the traditional RPM command:

sudo rpm -i viber.rpm

Handling Dependencies

During installation, you might encounter dependency-related issues. One common problem in Fedora 41 is the missing libcrypto.so.10 library. To resolve this, install the compat-openssl10 package:

sudo dnf install compat-openssl10

If you encounter additional dependency issues, you can try installing them with:

sudo dnf install libXScrnSaver libnotify

Verifying the Installation

After successful installation, verify that Viber is properly installed by searching for it in your application menu or running:

viber

The application should launch, presenting you with a QR code to link with your mobile device.

Method 2: Using Viber AppImage

AppImage is a universal software packaging format that allows applications to run on various Linux distributions without installation. This method is ideal if you prefer not to modify your system or want to try Viber without committing to a full installation.

Understanding AppImage Benefits

AppImage offers several advantages:

• No installation required
• No system modification
• Easy portability between Linux systems
• Self-contained dependencies
• Simple to update or remove

Downloading Viber AppImage

To get the Viber AppImage, use wget to download it:

wget -c https://download.cdn.viber.com/desktop/Linux/viber.AppImage

Making the AppImage Executable

After downloading, you need to make the AppImage file executable. Run the following command:

chmod +x viber.AppImage

Running Viber via AppImage

You can now run Viber directly by executing the AppImage:

./viber.AppImage

Creating a Desktop Shortcut

For convenience, you might want to create a desktop shortcut. Create a file named viber.desktop in ~/.local/share/applications/ with the following content:

[Desktop Entry]
Name=Viber
Comment=Viber VoIP and messaging application
Exec=/path/to/viber.AppImage
Icon=/path/to/viber-icon.png
Terminal=false
Type=Application
Categories=Network;InstantMessaging;

Replace /path/to/viber.AppImage with the actual path to your AppImage file. You can download a Viber icon from the internet for use with the shortcut.

Method 3: Using Unofficial Snap Package

Snap is a universal package management system developed by Canonical. While there’s no official Viber snap package, an unofficial one is available that works well on Fedora 41.

Setting Up Snapd on Fedora 41

First, install the snap daemon (snapd) on your Fedora system:

sudo dnf install snapd

After installation, enable the snapd service:

sudo systemctl enable --now snapd.socket

To enable classic snap support, create a symbolic link:

sudo ln -s /var/lib/snapd/snap /snap

You’ll need to log out and log back in, or restart your system, for the changes to take effect.

Installing Viber Snap Package

Once snapd is set up, install the unofficial Viber snap package:

sudo snap install viber-unofficial

The installation process may take a few minutes, depending on your internet connection speed.

Running Viber Snap

After installation, you can launch Viber either from your application menu or by running:

snap run viber-unofficial

Setting Up Viber After Installation

Regardless of which installation method you chose, you’ll need to set up Viber on your desktop by linking it to your mobile device.

First-Time Launch

When you launch Viber for the first time, you’ll see a welcome screen with a QR code. This code is used to link your desktop installation with your mobile device.

QR Code Scanning Process

To link your devices:

1. Open Viber on your mobile phone
2. Navigate to “More” (three dots or hamburger menu)
3. Select “Settings” > “Viber for Desktop”
4. Tap “Scan QR code”
5. Point your phone’s camera at the QR code displayed on your desktop screen

Account Verification

After scanning the QR code, your desktop application will sync with your mobile device, importing your contacts, chat history, and settings. This process may take a few minutes, depending on the amount of data.

Configuring Initial Settings

Once the synchronization is complete, you can configure your Viber desktop settings:

1. Adjust notification preferences
2. Set up audio and video devices for calls
3. Configure privacy settings
4. Customize the chat appearance and background
5. Set up backup options for your messages

Troubleshooting Common Issues

Even with careful installation, you might encounter some issues when using Viber on Fedora 41. Here are solutions to common problems:

Dependency Issues (libcrypto.so.10)

One of the most common issues is the missing libcrypto.so.10 library. This can be resolved by installing the compatibility package:
