先备份原始源，再替换为阿里云源即可。

Ubuntu 26.04（Resolute Raccoon）默认已经使用 .sources 格式，而不是老的 sources.list。

1. 备份原配置

bash 复制代码

sudo cp /etc/apt/sources.list.d/ubuntu.sources /etc/apt/sources.list.d/ubuntu.sources.bak

2. 编辑镜像源

bash 复制代码

sudo vim /etc/apt/sources.list.d/ubuntu.sources

将内容替换为：

yaml 复制代码

Types: deb
URIs: https://mirrors.aliyun.com/ubuntu/
Suites: resolute resolute-updates resolute-backports
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

Types: deb
URIs: https://mirrors.aliyun.com/ubuntu/
Suites: resolute-security
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

3. 更新缓存

bash 复制代码

sudo apt update

4. 验证是否生效

bash 复制代码

apt policy

或者：

bash 复制代码

grep -E "mirrors.aliyun.com" /etc/apt/sources.list.d/ubuntu.sources

一键脚本（推荐）

直接执行：

bash 复制代码

sudo bash -c 'cat > /etc/apt/sources.list.d/ubuntu.sources <<EOF
Types: deb
URIs: https://mirrors.aliyun.com/ubuntu/
Suites: resolute resolute-updates resolute-backports
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

Types: deb
URIs: https://mirrors.aliyun.com/ubuntu/
Suites: resolute-security
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
EOF'

sudo apt update
