我在使用 Enigmail 设置 Thunderbird 中的电子邮件加密时遇到了麻烦。我在另一台运行 Zorin 的 Linux 机器上创建了加密密钥，没有任何问题，并将其导出到我的外部硬盘驱动器。当我尝试将其导入到这台 Ubuntu 14.04 机器上的 Thunderbird 时，我转到 Enigmail、密钥管理、文件、导入 ~Files From Key。当我选择要导入的加密密钥时，我收到此消息，
Importing the keys failed
The key(s) were successfully imported

我认为问题在于我首先需要我的公钥，所以当我尝试下载它时出现此错误：
gpg: failed to create temporary file`/home/john/.gnupg/.#lk0x7fc50ebfbc70.john-desktop.8335': Permission denied
gpg: keyblock resource `/home/john/.gnupg/secring.gpg': General error

gpg: requesting key 2D10E96A from hkp server pool.sks-keyservers.netgpg: no writable keyring found: Unknown system error
gpg: error reading `[stream]': General error

即使我在这台机器上运行生成新密钥选项，也需要几个小时并给出以下错误消息：
密钥生成失败。请查看 Enigmail 控制台（菜单 Enigmail > 调试 Enigmail）了解详细信息。
答案1
这些不应由 root 拥有。您可以更改权限，这样应该就可以了。
要做到这一点：
打开一个终端，假设您的用户名是约翰，您将输入以下内容。
sudo chown -R john:john /home/john/.gnupg
再次运行，验证所有者是否从 root 更改为 john ls -al /home/john/。现在您应该能够毫无问题地导入它。
