On this short tutorial, we will discuss how to install Wireshark 3.4.2 (the lastes stable version so far) on Ubuntu 20.04 LTS Linux Operating system.

Introduction

Wireshark is a free and open-source network protocol analyzer. Previously known as Ethereal, Wireshark is used for network troubleshooting, analysis, software and communications protocol development, and education. Wireshark is cross-platform, using the Qt widget toolkit in current releases to implement its user interface, and using pcap to capture packets; it runs on Linux, macOS, BSD, Solaris, some other Unix-like operating systems, and Microsoft Windows. There is also a terminal-based (non-GUI) version called TShark.

WireShark Installation On Ubuntu 20.04 LTS

The WireShark installation will be consist of several steps as mentioned below :

1. Add The Wireshark Stable Repository
2. Install Wireshark
3. Configure Wireshark
4. Launch Wireshark

The installation process will be discussed in more detail in the sub-chapter below.

1. Add The Wireshark Stable Repository

On this stage, we will add Wireshark stable repository to our Ubuntu System. For this purpose we will submit the following command line :

$ sudo add-apt-repository ppa:wireshark-dev/stable

The output will be :

ramans@diginet-app02:~$ sudo add-apt-repository ppa:wireshark-dev/stable
[sudo] password for ramans: 
 Latest stable Wireshark releases back-ported from Debian package versions.

Back-porting script is available at https://github.com/rbalint/pkg-wireshark-ubuntu-ppa

From Ubuntu 16.04 you also need to enable "universe"  repository, see:

2. Install Wireshark

After all are set, then we will install Wireshark on our Ubuntu 20.04 system by submitting command line :

$ sudo apt -y install wireshark

Output :

ramans@diginet-app02:~$ sudo apt -y install wireshark

Package configuration

On this installation, we will be prompted to enable root privilege to other user. By default the status is disable, by pressing ‘Yes’ we will confirm to give other user account to have root privilege.

After installation was completed done, then we will check Wireshark version by submitting command line :

$ wireshark --version

Output :

ramans@diginet-app02:~$ wireshark --version

On this section, we will configure accounts who could use Wireshark. For this purpose, we have to add account(s) to the Wireshark group so that these users can use Wireshark. As our example we will add all user to be able to user Wireshark. To do this, we will submit the command line :


You must add a username to the Wireshark group so that this user can use Wireshark. To do this, execute the following command, adding your required username after “wireshark” in the command.

3. Configure Wireshark

On this stage, we will configure a new non root user system to be able to use Wireshark. For this purpose we will create a new user and give him a privilege to be able to run Wireshark.

ramans@diginet-app02:~$ sudo usermod -a -G wireshark $USER
[sudo] password for ramans: 
ramans@diginet-app02:~$ sudo chgrp wireshark /usr/bin/dumpcap
ramans@diginet-app02:~$ sudo chmod 750 /usr/bin/dumpcap
ramans@diginet-app02:~$ sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap
ramans@diginet-app02:~$ sudo getcap /usr/bin/dumpcap
/usr/bin/dumpcap = cap_net_admin,cap_net_raw+eip

4. Launch Wireshark Monitoring Tools

There are two options for running the Wireshark application on Ubuntu, namely: via the terminal/konsole or through the Graphical User Interface (GUI).

By using terminal or console, we will submit the command line :

$ wireshark

By using the GUI desktop, we just search Wireshark application, and double click it to launch. The application can be seen as shown below.

Conclusion

On this short tutorial, we have learn how to install Wireshark, a Network Analyzer tools on Ubuntu 20.04 operating system. I hope this article could be helpful.
