Install Wireshark 2.9.1 on Ubuntu (18.04 bionic, 18.10 Cuttlefish and 19.04 Dingo)

Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions. Wireshark development thrives thanks to the volunteer contributions of networking experts around the globe and is the continuation of a project started by Gerald Combs in 1998.

Wireshark has a rich feature set which includes the following:

• Deep inspection of hundreds of protocols, with more being added all the time
• Live capture and offline analysis
• Standard three-pane packet browser
• Multi-platform: Runs on Windows, Linux, macOS, Solaris, FreeBSD, NetBSD, and many others
• Captured network data can be browsed via a GUI, or via the TTY-mode TShark utility
• The most powerful display filters in the industry
• Rich VoIP analysis
• Read/write many different capture file formats: tcpdump (libpcap), Pcap NG, Catapult DCT2000, Cisco Secure IDS iplog, Microsoft Network Monitor, Network General Sniffer® (compressed and uncompressed), Sniffer® Pro, and NetXray®, Network Instruments Observer, NetScreen snoop, Novell LANalyzer, RADCOM WAN/LAN Analyzer, Shomiti/Finisar Surveyor, Tektronix K12xx, Visual Networks Visual UpTime, WildPackets EtherPeek/TokenPeek/AiroPeek, and many others
• Capture files compressed with gzip can be decompressed on the fly
• Live data can be read from Ethernet, IEEE 802.11, PPP/HDLC, ATM, Bluetooth, USB, Token Ring, Frame Relay, FDDI, and others (depending on your platform)
• Decryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2
• Coloring rules can be applied to the packet list for quick, intuitive analysis
• Output can be exported to XML, PostScript®, CSV, or plain text

How to Install Wireshark 2.9.1 on Ubuntu / Linux Mint system :

You can update your system with unsupported packages from this untrusted PPA by adding ppa:dreibh/ppa to your system's Software Sources. (Read about installing)

sudo add-apt-repository ppa:dreibh/ppa

sudo apt-get update

to install wireshak, do:

sudo apt-get install wireshark

There is a series of steps to follow that implement Privilege Separation, effectively allowing the Wireshark GUI to run as a normal user while dumpcap (which is collecting the packets from your interfaces) runs with the elevated privileges required to sniff. First, try:

sudo dpkg-reconfigure wireshark-common

And select Yes when prompted as to whether non-superusers should be able to capture packets.

In the event that this doesn’t do the trick, issue the following series of commands, which will configure the dumpcap executable to run. Be sure to include YOUR_USER_NAME where indicated below:

sudo chgrp YOUR_USER_NAME /usr/bin/dumpcap

sudo chmod +x /usr/bin/dumpcap

sudo setcap cap_net_raw,cap_net_admin+eip /usr/bin/dumpcap

After setting permision is finished, run wireshark and choose interface card :
