I m going to install wireshark from the following youtube video

sudo apt-get install wireshark libcap2-bin
sudo groupadd wirshark
sudo usermod -a -G wireshark debbase

But I faced problem while I ran the command sudo usermod -a -G wireshark debbase. It gives the error:

user 'debbase' does not exist

What should I do?

In this example, debbase is the provided username. Replace it with your username. This would be the one you entered when you installed and set up Ubuntu.

You can also find your username by entering a shell and typing:


What that command does is adds the user debbase to the group wireshark

debbase is the username of the individual in the tutorial.

You need to replace "debbase" with your local username.

If you aren't sure, you can type whoami in your terminal to get this information.
