Сбой стандартной команды: apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5

Я использую Docker, и я определил, что он не работает только в среде Docker.

$ docker run --rm -it --entrypoint bash resin/jetson-tx2-debian:stretch
root@8ddf33f82fee:/# apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5
Executing: /tmp/apt-key-gpghome.aflZmH62Gv/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5
gpg: keyserver receive failed: Connection refused

Это похоже на проблему с тем, как dirmngr использует DNS-серверы. https://dev.gnupg.org/T3374 Внесение изменений в resolv.conf, кажется, помогает:

# Changed to only include "nameserver 8.8.8.8"
root@8ddf33f82fee:/# nano /etc/resolv.conf

И наконец успех

root@8ddf33f82fee:/# apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5
Executing: /tmp/apt-key-gpghome.LQgK0o5ZBJ/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5

У меня вопрос, какое уместное решение здесь? Мои пакеты, кажется, обновлены, но эти ошибки сохраняются.
