Question

我按照docker官方说明从https://docs.docker.com/install/linux/docker-ce/ubuntu/在ubuntu 18.04 LTS上安装docker

使用我运行的设置存储库：

sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common

和

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

和结局

sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

然后，运行 sudo apt-get update 我遇到错误：

我无法使用：

安装docker

sudo apt-get install docker-ce docker-ce-cli containerd.io

我该怎么做才能读取这些错误并返回到正常配置？

谢谢。

Answer 1

我可以在https://chrisjean.com/fix-apt-get-update-the-following-signatures-couldnt-be-verified-because-the-public-key-is-not-available/

之后解决此问题

简而言之：查看上面的错误，apt告诉我们缺少以下密钥：3B4FE6ACC0B21F32。请注意，这些被多次列出。每个唯一键只需添加一次。

要添加这些键，我运行了以下命令：

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5

Answer 2

在遵循了https://thecodecloud.in/solved-apt-get-update-the-following-signatures-couldnt-be-verified-because-the-public-key-is-not-available/

之后，我解决了此问题

我在更新ubuntu存储库时检查了确切的错误。然后我使用下面的命令成功运行，同时我们必须从错误中复制密钥并粘贴到下面的命令中。

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys ????????????????

apt-get更新的签名验证期间发生错误
