我试图更新apt get以安装salt minion，但我收到错误GPG错误：精确版本：无法验证以下签名，因为公钥不可用：NO_PUBKEY 0E08A149DE57BFBE，因此我无法更新并安装我需要的内容

你知道我该怎么解决这个问题吗

谢谢

运行

sudo apt key adv--keyserver keyserver.ubuntu.com--recv keys 0E08A149DE57BFBE

然后

sudo-apt-get-update

---

第一种方式：

尝试添加缺少的密钥：

     sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 0E08A149DE57BFBE

然后进行更新：

     sudo apt-get update

第二种方式：

如果它是一个无用的包，请尝试从/etc/apt/sources.list和此文件夹中删除：

cd/etc/apt/sources.list.d
