wireshark: no interface can be used for capturing in this system

ubuntu14.04下使用wireshark找不到网卡。。。

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.
