Issue with GPG keys

[alexalv]

Hello, for some reason my builds always fail on
RUN gpg --batch --keyserver hkps://hkps.pool.sks-keyservers.net --recv-keys CD8CB0F1E0AD5B52E93F41E7EA93F5E56E751E9B

I am trying to build an alpine image with arangodb3-client installed, but I cannot get past this gpg step.
Example dummy dockerfile that fails for me:

FROM alpine:3.8

# instal arango client
ENV ARANGO_VERSION 3.4.5
ENV ARANGO_URL https://download.arangodb.com/arangodb34/DEBIAN/amd64
ENV ARANGO_PACKAGE arangodb3-client_${ARANGO_VERSION}-1_amd64.deb
ENV ARANGO_PACKAGE_URL ${ARANGO_URL}/${ARANGO_PACKAGE}
ENV ARANGO_SIGNATURE_URL ${ARANGO_PACKAGE_URL}.asc

RUN apk add --no-cache gnupg pwgen nodejs npm binutils && \
    npm install -g foxx-cli && \
    rm -rf /root/.npm

RUN gpg --batch --keyserver hkps://hkps.pool.sks-keyservers.net --recv-keys CD8CB0F1E0AD5B52E93F41E7EA93F5E56E751E9B

RUN cd /tmp                                && \
    wget ${ARANGO_SIGNATURE_URL}           && \
    wget ${ARANGO_PACKAGE_URL}             && \
    gpg --verify ${ARANGO_PACKAGE}.asc     && \
    ar x ${ARANGO_PACKAGE} data.tar.gz     && \
    tar -C / -x -z -f data.tar.gz          && \
    rm -f ${ARANGO_PACKAGE}* data.tar.gz

And the log of docker build

The dockerfile I copypasted from one of the templates in this repo, tried going to http://hkps.pool.sks-keyservers.net/ and searching for the key with CD8CB0F1E0AD5B52E93F41E7EA93F5E56E751E9B signature - got a Not found error

Not sure what am I doing wrong, any ideas?

Looks like the keyserver pool hkps://hkps.pool.sks-keyservers.net is down atm.

You could try another pool

gpg --keyserver ipv4.pool.sks-keyservers.net --recv-keys CD8CB0F1E0AD5B52E93F41E7EA93F5E56E751E9B

Or download the public key from arangodb repository

curl https://download.arangodb.com/arangodb34/DEBIAN/Release.key | gpg --import \
&& gpg --fingerprint CD8CB0F1E0AD5B52E93F41E7EA93F5E56E751E9B
