can‘t read /etc/apt/sources.list: No such file or directory

使用第二种方法现在直接报错了

对，这次的报错是合理的，不是网络问题，是我们“换源那一行”写得太老了：

sed: can't read /etc/apt/sources.list: No such file or directory

原因：现在的 python:3.11-slim 基于比较新的 Debian（bookworm/trixie），它已经用 /etc/apt/sources.list.d/debian.sources 这种新格式了，根本没有传统的 /etc/apt/sources.list，所以你一 sed 就报错。

给你一份能在这类 slim 镜像上跑的 兼容写法，直接用👇这个 Dockerfile：

FROM python:3.11-slim

# 1. 替换源（兼容老文件和 debian.sources）
RUN if [ -f /etc/apt/sources.list ]; then \
        sed -i 's@deb.debian.org@mirrors.aliyun.com@g' /etc/apt/sources.list && \
        sed -i 's@security.debian.org@mirrors.aliyun.com@g' /etc/apt/sources.list ; \
    elif [ -f /etc/apt/sources.list.d/debian.sources ]; then \
        sed -i 's@deb.debian.org@mirrors.aliyun.com@g' /etc/apt/sources.list.d/debian.sources && \
        sed -i 's@security.debian.org@mirrors.aliyun.com@g' /etc/apt/sources.list.d/debian.sources ; \
    else \
        echo "no apt source file found"; \
    fi \
    && apt-get update \
    && apt-get install -y --no-install-recommends \
        libreoffice-writer \
        libreoffice-impress \
        libreoffice-calc \
        fonts-dejavu \
        imagemagick \
    && rm -rf /var/lib/apt/lists/*

要点讲清楚：
1. 先判断 /etc/apt/sources.list 在不在，在就 sed 它；
2. 不在就改 /etc/apt/sources.list.d/debian.sources；
3. 再 apt-get update，再装 libreoffice。
