There are no interfaces on which a capture can be done

解决方法:

Open a terminal by pressing Ctrl+Alt+T and type the following commands:

sudo dpkg-reconfigure wireshark-common

press the right arrow and enter for yes

sudo chmod +x /usr/bin/dumpcap

you should now be able to run it without root and you will be able to capture.

然后  重启wireshark
