跳过位于 /etc/apt/apt.conf.d 文件夹中的 50unattended-upgrades_ucf_dist 文件

在Ubuntu系统中安装OpenCV教程可供参考：http://docs.opencv.org/2.4/doc/tutorials/introduction/linux_install/linux_install.html

ubuntu 安装opencv的时候,终端运行命令:

     sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

出现错误:
