忽略‘50unattended

ubuntu 安装opencv教程可以参考:.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

错误:1 xenial/universe amd64 libtbb-dev amd64 4.4~20151115-0ubuntu3
  404  Not Found [IP: 115.28.122.210 80]
N: 忽略‘50unattended-upgrades.ucf-dist’(于目录‘/etc/apt/apt.conf.d/’)，鉴于它的文件扩展名无效
E: 下载 .4~20151115-0ubuntu3_amd64.deb  404  Not Found [IP: 115.28.122.210 80] 失败

解决方法是删除目录/etc/apt/apt.conf.d/下的文件50unattended-upgrades.ucf-dist,即在终端运行命令:

sudo rm /etc/apt/apt.conf.d/50unattended-upgrades.ucf-dist

之后重新运行:

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

安装成功.
