Hi,
for 3 days our CI pipelines to recreate Docker images fails for the Hirsute
images. 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

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.
