I'm trying build a docker container with the following command:
sudo docker build docker_calculadora/but when it's building, at the step 9 it appears the following error:
Step 9/27 : RUN set -ex; export GNUPGHOME="$(mktemp -d)"; for key in $GPG_KEYS; do gpg --batch --keyserver ha.pool.sks-keyservers.net --recv-keys "$key"; done; gpg --batch --export $GPG_KEYS > /etc/apt/trusted.gpg.d/mariadb.gpg; command -v gpgconf > /dev/null && gpgconf --kill all || :; rm -r "$GNUPGHOME"; apt-key list ---> Running in a80677ab986c
