E: Unable to locate package libjasper-dev

[sunwenzheng]

近期需要在ubuntu18.04系统上安装opencv但是在安装依赖包的过程中，有一个依赖包，libjasper-dev在使用命令

sudo apt-get install libjaster-dev

提示：errorE: unable to locate libjasper-dev

后来google到解决办法，复制到这里

sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
sudo apt update
sudo apt install libjasper1 libjasper-dev

成功的解决了问题，其中libjasper1是libjasper-dev的依赖包
