NO_PUBKEY as result of apt-get update

[reisenmachtfreude]

I've trouble using the mongo docker image. If an apt-get update is executed, it says that the keys are missing

Ugly workaround

FROM mongo

RUN mv /etc/apt/sources.list.d/mongodb-org.list /mongodb-org.list 
RUN apt-get update -y
RUN apt-get install wget
RUN wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | apt-key add -
RUN mv /mongodb-org.list /etc/apt/sources.list.d/mongodb-org.list
RUN apt-get upgrade -y

Upstream had used the 4.4 key on the 5.0 repo. Now it is fixed upstream. We added the 5.0 key (77032bf) and the published images will have the change soon (docker-library/official-images#10552).
