arm64 image broken for Consul 1.8

[snesbittsea]

Tried to create a Consul 1.8 docker container on an arm64 (aarch64) machine (raspberry pi 4) today without success as follows: docker run --rm consul:1.8
All attempts lead to a single error message "==> operation not permitted"

Creating a container using 1.7 (docker run --rm consul:1.7) works as expected.

Underlying system is ubuntu 20.04.
Docker version 19.03.8, build afacb8b7f0
