基于ubuntu/python:3.12-24.04_stable镜像构建Docker镜像时出现/bin/sh不存在及exit code:1错误的求助

我现在在用ubuntu/python:3.12-24.04_stable这个Docker镜像，写了个非常简单的Dockerfile：

FROM ubuntu/python:3.12-24.04_stable

RUN apk update

结果执行构建的时候直接返回了exit code: 1，错误提示说找不到/bin/sh，这可把我搞懵了。

以下是我执行的构建命令和完整的错误输出：

docker build -t test -f Dockerfile .

我之前试过python:3.12和ubuntu:24.04这两个镜像，执行类似的RUN命令都完全没问题，唯独这个ubuntu/python:3.12-24.04_stable一跑RUN就出这种错，难道这个镜像里真的没有/bin/sh吗？
