Ошибка при проверке подписи обновления apt-get
Я следую официальным инструкциям докера для установки докера на Ubuntu 18.04 LTS с https://docs.docker.com/install/linux/docker-ce/ubuntu/
Используя установочный репозиторий, я запустил:
sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg-agent \
software-properties-common
а также
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
и наконец
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
Затем при запуске обновления sudo apt-get у меня появляются ошибки:

и я не смог установить докер используя:
sudo apt-get install docker-ce docker-ce-cli containerd.io
Что я должен сделать, чтобы прочитать об этой ошибке и вернуться к нормальной конфигурации?
Заранее спасибо.

Я мог бы решить эту проблему, следуя https://chrisjean.com/fix-apt-get-update-the-following-signatures-couldnt-be-verified-because-the-public-key-is-not-available/
Вкратце: Посмотрев на ошибку выше, apt сообщает, что отсутствуют следующие ключи: 3B4FE6ACC0B21F32. Обратите внимание, что они перечислены несколько раз. Каждый уникальный ключ нужно будет добавить только один раз.
Чтобы добавить эти ключи, я запустил следующие команды:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5
Я исправил эту проблему после того, как https://thecodecloud.in/solved-apt-get-update-the-following-signatures-couldnt-be-verified-because-the-public-key-is-not-available/
Я проверил точную ошибку при обновлении репозитория ubuntu. Затем я использовал приведенную ниже команду, которая успешно сработала, пока нам нужно скопировать ключ из ошибки и вставить команду ниже.
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys ????????????????
