gnupg – Blackbox：GPG解密失败(不知道ctb = 00)

我正在运行GitLab CI部署脚本,而blackbox_postdeploy失败并显示消息gpg：[不知道] ctb = 00.

我已经能够发现ctb = 00通常与损坏的钥匙串有关,但由于我在一个干净的Docker容器(通过GitLab CI)上运行它,我不知道如何解决它.

这是GitLab CI脚本的输出：

$gpg -v --import <(echo "$GPG_PRIVATE_KEY")

我试过的事情：

>手动删除Blackbox文件.
>强制重新初始化存储库中的Blackbox.
>为我的部署机器人重新创建公钥.
>在部署之前删除容器上的/root/.gnupg-folder.

有人可以帮助我吗？这偶尔会打破我的存储库,对我的开发过程来说是一个巨大的痛苦.

谢谢.
