ubuntu1804系统（xavier、NX）编译opencv报E:Unable to locate package libjasper-dev等最新解决方法

opencv依赖包安装

sudo apt install libjasper1 libjasper-dev

报错：

使用《Xavier NX安装opencv3.4.7》里说的解决方法~不行：

新的解决方法：

1.sudo gedit /etc/apt/sources.list

2.在sources.list文件最后面 添加：

deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial-security main multiverse restricted universe
