我想libc6:i386通过dockfile安装，但不知道为什么总是失败。执行sudo docker run -it --rm debian:bookworm bash并进入容器时，我使用apt search libc6-i386搜索，可以找到libc6:i386.

答案1
问题是这样的：
1.811 Do you want to continue? [Y/n] Abort.
apt在继续之前需要确认，但由于它以非交互方式运行，因此它采用安全选项并退出。不仅如此，它还会因错误而退出，因此整个构建失败。
你需要告诉apt假设“是”的答案；这就是-y前面命令中使用的选项的用途。
RUN apt-get install -y libc6:i386
RUN apt-get install -y lib32stdc++6
或者
RUN apt-get install -y libc6:i386 lib32stdc++6
