问题 I've created a Dockerfile to install IBM Rational Rhapsody on a 32bit Ubuntu image, which builds correctly with Docker 18.03.0-ce on Windows 7 but fails with Docker 18.09.2 on a Linux Mint 19 VM (Ubuntu Bionic repos). IBM's Java-based installer throws a permissions issue, and the Docker changelogs didn't show any obvious reasons for this. The Dockerfile up to the failing command is as follows: FROM i386/ubuntu:xenial-20181005 AS installation ARG DEBIAN_FRONTEND=noninteractive RUN apt-get
