ERROR: Could not find a version that satisfies the requirement tcpdump (from versions: none) ERROR: No matching distribution found for tcpdump

tcpdump is not a Python package and cannot be installed using pip. It is a command-line tool that can be installed on your system using your system's package manager. For example, on Ubuntu you can install tcpdump using the following command:

sudo apt-get install tcpdump

On other systems, you may need to use a different package manager or installation method. Once tcpdump is installed, you can use it from the command line to capture network traffic.
