方法一：一键脚本配置
#!/bin/bash
# 备份原有配置
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup.$(date +%Y%m%d%H%M%S)
# 写入阿里云源配置
sudo tee /etc/apt/sources.list <<'EOF'
deb https://mirrors.aliyun.com/ubuntu/ noble main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ noble-updates main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ noble-backports main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ noble-security main restricted universe multiverse
EOF
# 更新缓存
sudo apt update
sudo apt upgrade -y
方法二：命令行配置
第 1 步：备份原有源配置
# 备份原有源列表
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
第 2 步：编辑软件源列表
# 使用 vi 编辑器打开源列表文件
sudo vi /etc/apt/sources.list
第 3 步：替换为阿里云源
将文件内容替换为以下内容：
# 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.aliyun.com/ubuntu/ noble main restricted universe multiverse
# deb-src https://mirrors.aliyun.com/ubuntu/ noble main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ noble-updates main restricted universe multiverse
# deb-src https://mirrors.aliyun.com/ubuntu/ noble-updates main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ noble-backports main restricted universe multiverse
# deb-src https://mirrors.aliyun.com/ubuntu/ noble-backports main restricted universe multiverse
deb https://mirrors.aliyun.com/ubuntu/ noble-security main restricted universe multiverse
# deb-src https://mirrors.aliyun.com/ubuntu/ noble-security main restricted universe multiverse
