Ubuntu18.04 + OpenCV + Jetson Nano/Raspberry Pi :Unable to locate package libjasper-dev

在Jetson Nano上安装opencv依赖库时遇到这样的问题

Unable to locate package libjasper-dev

执行以下代码，已经改成了清华源

sudo add-apt-repository "deb http://mirrors.tuna.tsinghua.edu.cn//ubuntu-ports xenial-security main"
sudo apt update
sudo apt install libjasper1 libjasper-dev
