Install Wireshark on Fedora Linux via DNF

Step 1: Update Fedora Packages Before Wireshark Installation

To begin, update your Fedora system packages. This step is crucial for maintaining compatibility and avoiding conflicts, as Fedora frequently updates its packages.

Execute the command below in your terminal:

sudo dnf upgrade --refresh

Step 2: Install Wireshark via DNF Command

Wireshark is readily available in Fedora’s repository. This accessibility simplifies installation and ensures easy updates.

Use the command below to install Wireshark:

sudo dnf install wireshark

For those needing additional features, the Wireshark developer (devel) package is also an option:

sudo dnf install wireshark-devel

After installation, verify its success and check the installed version of Wireshark with the following:

wireshark -v

Step 3: Adding User to Wireshark Group

To run Wireshark without permission issues, add your username to the Wireshark group. Neglecting this step could result in errors, such as being unable to start recordings due to permission denials.

Initially, switch to the root account:

su

If you’ve forgotten or never set a root password, establish one with:

sudo passwd root

Then, access the root account again with the su command.

Now, execute this command to add your username to the Wireshark group, replacing _your_username_ with your actual username:

usermod -a -G wireshark _your_username_

For example, if your username is ‘joshua’:

usermod -a -G wireshark joshua

After completing this step, log back into your regular account:

su <account name>

For example:

su joshua

An alternative way is just using the following command.

sudo usermod -a -G wireshark _your_username_

Alternatively, you can add your username to the Wireshark group using a single command:

sudo usermod -a -G wireshark _your_username_

This approach ensures you have the necessary permissions to run Wireshark effectively on Fedora Linux.
