Authentication is required to run /usr/bin/x-terminal-emulator as root

在安装kali的过程中遇到问题：Authentication is required to run /usr/bin/x-terminal-emulator as root

An application is attempting to perform an action that requiresprivileges.Authentication is required to perform this action.

如图所示：原因我感觉是因为没有设置root用户密码

 解决办法：我们只需要打开终端设置一个新的root密码即可，命令为：

sudo passwd root
