Docker 内 Ubuntu 24.04 更换阿里云 APT 源

Ubuntu 22.04+ 使用 deb822 格式源文件，路径默认是 /etc/apt/sources.list.d/ubuntu.sources，不再是旧版 sources.list。

一、Ubuntu 22.04 Jammy 阿里云源 Dockerfile

dockerfile

FROM ubuntu:22.04

# 清空原有源，写入阿里云deb822格式源
RUN echo > /etc/apt/sources.list.d/ubuntu.sources && \
    cat > /etc/apt/sources.list.d/ubuntu.sources <<EOF
Types: deb
URIs: https://mirrors.aliyun.com/ubuntu
Suites: jammy jammy-security jammy-updates jammy-backports
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
EOF

# 更新软件源
RUN apt update && apt upgrade -y

二、Ubuntu 24.04 Noble 阿里云源 Dockerfile

dockerfile

FROM ubuntu:24.04

RUN echo > /etc/apt/sources.list.d/ubuntu.sources && \
    cat > /etc/apt/sources.list.d/ubuntu.sources <<EOF
Types: deb
URIs: https://mirrors.aliyun.com/ubuntu
Suites: noble noble-security noble-updates noble-backports
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
EOF

RUN apt update

三、国内内网镜像（可选，阿里内网环境）

将 https://mirrors.aliyun.com/ubuntu 替换为

https://mirrors.aliyuncs.com/ubuntu

四、如果需要同时注释掉旧版 sources.list（兼容写法）

dockerfile

RUN sed -i 's/^/#/' /etc/apt/sources.list && \
    echo > /etc/apt/sources.list.d/ubuntu.sources && \
    cat > /etc/apt/sources.list.d/ubuntu.sources <<EOF
Types: deb
URIs: https://mirrors.aliyun.com/ubuntu
Suites: jammy jammy-security jammy-updates jammy-backports
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
EOF

五、极简一行版（直接 COPY 文件）

1. 本地新建 ubuntu.sources 文件粘贴对应版本源
2. Dockerfile：

dockerfile

COPY ubuntu.sources /etc/apt/sources.list.d/ubuntu.sources
RUN apt update
