原理：

根據清華源提供的Ubuntu 軟件倉庫進行sources.list替換

ubuntu | 鏡像站使用幫助 | 清華大學開源軟件鏡像站 | Tsinghua Open Source Mirror

1、換源

echo "">/etc/apt/sources.list \&& echo "# 默認注釋了源碼鏡像以提高 apt update 速度，如有需要可自行取消注釋">>/etc/apt/sources.list \&& echo "deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse">>/etc/apt/sources.list \&& echo "# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy main restricted universe multiverse">>/etc/apt/sources.list \&& echo "deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse">>/etc/apt/sources.list \&& echo "# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-updates main restricted universe multiverse">>/etc/apt/sources.list \&& echo "deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse">>/etc/apt/sources.list \&& echo "# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse">>/etc/apt/sources.list \&& echo "deb http://security.ubuntu.com/ubuntu/ jammy-security main restricted universe multiverse">>/etc/apt/sources.list \&& echo "# deb-src http://security.ubuntu.com/ubuntu/ jammy-security main restricted universe multiverse">>/etc/apt/sources.list \&& echo "# 預發布軟件源，不建議啟用">>/etc/apt/sources.list \&& echo "# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse">>/etc/apt/sources.list \&& echo "# # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-proposed main restricted universe multiverse">>/etc/apt/sources.list

2、更新軟件列表

apt-get clean && apt-get update
