测试了，是可以的，不是 arm 环境是 x86 环境。我觉得硬替换应该没问题吧

印象里 ubuntu-ports 的默认源是不带 cn 的，还是要之后确认一下。这个 PR 暂且搁置。

ubuntu-ports 默认源都是类似 deb http://ports.ubuntu.com/ubuntu-ports/ focal main restricted 这种。
这个可以用docker很容易看到，如
docker run -it --rm ubuntu@sha256:26c3bd3ae441c873a210200bcbb975ffd2bbf0c0841a4584f4476c8a5b8f3d99 cat /etc/apt/sources.list
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
deb http://ports.ubuntu.com/ubuntu-ports/ focal main restricted
# deb-src http://ports.ubuntu.com/ubuntu-ports/ focal main restricted
## Major bug fix updates produced after the final release of the
## distribution.
deb http://ports.ubuntu.com/ubuntu-ports/ focal-updates main restricted

## Uncomment the following two lines to add software from Canonical's
## 'partner' repository.

# deb http://archive.canonical.com/ubuntu focal partner

deb http://ports.ubuntu.com/ubuntu-ports/ focal-security multiverse
# deb-src http://ports.ubuntu.com/ubuntu-ports/ focal-security multiverse
所以应该使用类似 sudo sed -i 's|ports.ubuntu.com|mirror.sjtu.edu.cn|g' /etc/apt/sources.list 进行一键替换。

争取过几天去真机 例如树莓派 nVidia开发板上面跑跑看

其实 ubuntu 源里有个cn就很奇怪，镜像里都是没有的，所以这应该是本地初始化时加的，脚本里直接绝对匹配cn这不合理。
ports也有http://cn.ports.ubuntu.com/ 的源。树莓派镜像里没有桌面环境，安装后没有本地化引导应该不会加cn。
sed -i 's|\(cn.\)\?ports.ubuntu.com|mirror.sjtu.edu.cn|g' /etc/apt/sources.list
可选cn就行了（按理说在基本正则里.是通配符，好多人都没打转义符直接用，我也懒得打了）
