If you installed Wireshark using the package from wireshark.org, close this dialog and click on the "installing ChmodBPF" link in "You can fix this by installing ChmodBPF." on the main screen, and then complete the installation procedure.

解决办法

sudo chmod 777 /dev/bpf*

重新打开软件后可以看到网卡流量有变化了。

系统重启后需要重新操作。
