Comment 13 for bug 1867675

This is a problem on Docker with armhf hosts when building new images using the `ubuntu:focal` image from Docker Hub[1]. Images will fail to build because of the reported error

I've included the error that results from running `docker build` on a Dockerfile referencing `ubuntu:focal` and installing libcrypt1

Images will build using the `ubuntu:rolling` image.

Host details:
Ubuntu 18.04.4 LTS
Docker version 19.03.11, build 42e35e6

[1] Exact image: https://hub.docker.com/layers/ubuntu/library/ubuntu/focal/images/sha256-5747316366b8cc9e3021cd7286f42b2d6d81e3d743e2ab571f55bcd5df788cc8?context=explore
