GPG 错误，签名公钥不可用，尝试了很多次

我尝试过许多旧问题推荐的解决方案，但似乎没有任何帮助。

  • sudo apt-get clean

  • sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 40976EAF437D05B5 （包含所有缺失的密钥）

  • 我安装了launchpad-getkeys 启动器它应该自动恢复密钥

有任何想法吗？

答案1

Ubuntu 中的当前apt正遭受apt 中的 gpg 资源限制错误

您可以轻松修复此问题，/etc/apt/trusted.gpg.d并删除未使用的密钥（通常来自不再使用的 PPA），直到密钥数量低于 40 个。

然后跑了sudo apt-get update

答案2

您可能受到以下影响错误 1263540。我建议你尝试一下：

  1. sudo apt-get clean
  2. sudo mv /var/lib/apt/lists /var/lib/apt/lists.old
  3. mkdir -p /var/lib/apt/lists/partial
  4. 删除 /etc/apt/trusted.gpg.d/ 中的所有 0 长度文件
  5. sudo apt-get 更新

如果不起作用，请恢复步骤 2 中备份的 /var/lib/apt/lists。
