Solve the problem that Wireshark cannot be used to capture packets in Ubuntu.

After Wireshark is installed in Ubuntu, the NIC information cannot be found during running. The reason is that my account is a common user and does not have the root permission. In this way, Wireshark does not have the permission to obtain the NIC parameters in a normal user's environment.

The solution is to use sudo Wireshark in the terminal.

For example:

Wireshark tool for starting packet capture has been enabled
