Ubuntu 是一个广泛使用的开源操作系统，有许多国内镜像源可供选择。主要有：清华大学开源软件镜像站、中科大镜像站、阿里云镜像站等，这些镜像站都提供 Ubuntu 软件仓库的镜像，用于加速 ubuntu 各软件的安装、更新等操作。执行软件仓库更新前，建议执行 mv /etc/apt/sources.list /etc/apt/sources.list.bak备份默认软件仓库

清华

清华大学开源软件镜像站

因镜像站同步有延迟，可能会导致生产环境系统不能及时检查、安装上最新的安全更新，不建议替换 security 源

因镜像站同步有延迟，可能会导致生产环境系统不能及时检查、安装上最新的安全更新，不建议替换 security 源。 如果有官方源下载速度不理想等问题，想通过镜像站下载安全更新， 可以将 security 源地址从 http://security.ubuntu.com/ 替换为 https://mirrors.ustc.edu.cn/，即 sudo sed -i ‘s/security.ubuntu.com/mirrors.ustc.edu.cn/g’ /etc/apt/sources.list
