所以我正在使用Docker进行项目，并且需要安装Python。
以前，当我的基本容器为ubuntu：18.04时，此方法工作正常
包裹被这样包裹：
FROM ubuntu:18.04
ENV DEBIAN_FRONTEND=noninteractive
RUN apt-get update && apt-get install -y --no-
install-recommends \
python \
...
我的项目还将包括Swift，因此我像这样更改了基本图像：
FROM swift:5.1
现在，当apt-get尝试安装python时，出现以下错误：
Errors were encountered while processing: /var/cache/apt/archives/python2.7-minimal_2.7.17-1~18.04_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
swift：5.1的Dockerfile可以在这里找到：
这也是基于ubuntu：18.04，所以我认为问题一定是由该dockerfile中的某些东西引起的。
我最好的猜测是，也许是因为swift：5.1还安装了libpython2.7
此错误究竟是什么？如何避免该错误？
编辑：这是出现错误的上下文：
