更换软件源

本文以 Ubuntu 操作系统为例,介绍如何更换软件源。

更改软件源文件

访问 清华大学 Ubuntu 软件源,选择操作系统等配置,然后复制代码块中的内容(一般安装的 Ubuntu 桌面版使用「传统格式」的即可)

打开终端,输入以下命令(将以下高亮的部分替换为你复制的内容,下面仅列举了默认配置下的部分 Ubuntu 版本参考代码)

bash
cat << EOF > /etc/apt/sources.list
# 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/ noble main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ noble main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ noble-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ noble-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ noble-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ noble-backports main restricted universe multiverse

# 以下安全更新软件源包含了官方源与镜像站配置,如有需要可自行修改注释切换

应用更改

随后更新软件包列表即可:

bash
sudo apt-get update
