Jetson换镜像源

因为工作需要，我想把之前Jetson Orin Nano上OpenCV4.5.4 升级到OpenCV4.8。先到这里下载脚本

wget https://github.com/Qengineering/Install-OpenCV-Jetson-Nano/raw/main/OpenCV-4-8-0.sh

然后我尝试运行这个脚本

./OpenCV-4-8-0.sh

结果告诉无法访问官方的ubuntu.port的网站，我晕倒！

然后我听说可以换镜像源，先找到etc/apt/source.list这个文件所在的文件夹，然后先执行：

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

再执行：

sudo gedit /etc/apt/sources.list

然后找到对应的源文件，推荐用这里的

https://mirror.tuna.tsinghua.edu.cn/help/ubuntu/

打开上面的链接，然后选择如下：

然后copy上面代码部分的内容直接替换：

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal-backports main restricted universe multiverse

deb http://ports.ubuntu.com/ubuntu-ports/ focal-security main restricted universe multiverse
# deb-src http://ports.ubuntu.com/ubuntu-ports/ focal-security main restricted universe multiverse

# 预发布软件源，不建议启用
# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal-proposed main restricted universe multiverse
# # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal-proposed main restricted universe multiverse

替换完成以后，保存以后一定要运行下面两句话：
