OK; I did not see that gpg was actually installed. Please report bugs properly with ubuntu-bug/apport next time instead of dumping data in the text report.

From comparison this seems to be caused by apt 2.1.20. The build fails with: 0E: gnupg, gnupg2 and unupg1 do not seem to be installed, but one of them is required for this operation The simple Dockerfile to reproduce the error - "docker build -t foo ." FROM amd64/ubuntu:hirsute MAINTAINER Florian Lohoff <f...@zz.de> USER root RUN apt-get update \ && DEBIAN_FRONTEND=noninteractive apt-get -y install curl gnupg apt \ && curl https://syncthing.net/release-key.txt | apt-key add - Breaking it down it this seems to be an issue that there is new functionality in apt/apt-key e.g. security hardening that docker prohibits in its containers. Running this manually works only in an --privileged container. So adding keys in unpriviledged container or possibly kubernetes will not work anymore.
