无法解决GPG错误

Question

我运行了sudo apt-get update，最后出现了以下错误：

看来我丢失的钥匙是：

• 40976EAF437D05B5
• 3B4FE6ACC0B21F32
• 16126D3A3E5C1192
• A040830F7FAC5991
• A8A515F046D7E7CF
• E131728675254D99

我看到大多数答案都说要跑：

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys [MISSING KEY]

我查了一下：

我能看到unchanged: 1。

我还尝试使用y-ppa-manager，这也没有解决问题。

是什么导致了这些错误，我如何解决它们？

Answer 1

在我看来，这就像跟随错误。

如何修正

在错误报告中修复它的用户：

对我起作用的解决方案是清空/etc/apt/trud.gpg.d，运行apt-get更新，然后手动将它阻止的每个键添加到主/etc/apt/trud.gpg密钥环中，其中包含apt-key adv，如上所述。

因此，在您的情况下，您应该执行以下操作(免责声明:无法测试)：

sudo mv /etc/apt/trusted.gpg.d/ /etc/apt/trusted.gpg.d.backup
sudo mkdir /etc/apt/trusted.gpg.d
sudo chmod 755 /etc/apt/trusted.gpg.d

然后，对于您需要的每个键：

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

将哈希替换为所需密钥的哈希。正如IonicăBizău所指出的，可以添加多个键，用空格分隔。

为什么会出现

显然，gpg只能处理有限数量的钥匙圈，您的安装需要更多。这可能是由于有许多可供选择的数据包源造成的。

同样，在bug报告中：

I asked about the "resource limit" message on the gnupg-users mailing list...
Based on Werner Koch's (the dev) answer...
...the secure apt related programs might be making gpg use more than the maximum number of keyrings that it can handle

Answer 2

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys [MISSING KEY]为我工作。
