在我的 Ubuntu 14.04 64 位安装中安装 Xubuntu/Xfce 桌面环境后，我现在在运行更新时获得了缺少的公钥和错误的列表。
我注意到 Synaptic Package Manage 中缺少所有 ubuntu 密钥。列表中没有具有公钥的软件。
无论我登录 Unity 还是 Xubuntu 环境，都会出现同样的问题

Codename: trusty
我不认为这是重复的，因为这里没有任何解决方案起作用并且我所有的键都丢失了？

我努力了：
使用 Y PPA Manager 中的 FIX 功能
还有这个

sudo apt-get update | grep "NO_PUBKEY" | awk '{ system("addgpg-apt "$21) }'
我尝试使用软件和更新实用程序恢复默认密钥，然后再次尝试上述所有操作，但仍然存在同样的问题......所有密钥都消失了。
仍然是同样的问题...任何想法都将不胜感激..
谢谢

您可能会受到这个错误如果是的话，您可以通过转到/etc/apt/trusted.gpg.d/并删除未使用的密钥（例如，您已删除的旧 PPA 的密钥）轻松修复该问题。
如果 中有超过 40 个密钥 (*.gpg)，就会出现此错误/etc/apt/trusted.gpg.d/。
