无法解决与前端xxx： rpc错误：代码=未知desc=（...）out：'退出状态2： gpg：解密失败：没有密钥'

Question

我想使用Docker BuidlKit的一个实验功能（安装=类型=缓存）

我的Dockerfile的第一行是：

    # syntax=docker/dockerfile:experimental
    FROM i386/debian:buster

    #
    # Setup an apt cache for Docker (experimental)
    #
    RUN rm -f /etc/apt/apt.conf.d/docker-clean; echo 'Binary::apt::APT::Keep-Downloaded-Packages "true";' > /etc/apt/apt.conf.d/keep-cache
    RUN --mount=type=cache,target=/var/cache/apt --mount=type=cache,target=/var/lib/apt apt update && apt-get --no-install-recommends install -y gcc

我已经为docker设置了密码存储，成功登录到docker hub，“docker credential pass”二进制文件在我的路径中，设置“docker登录过程使用加密密码”。（如中所述）

“如何启用Docker实验功能并加密您的登录凭据”

    kalou@shinwey $ pass list
    Password Store
    `-- docker-credential-helpers
        |-- xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
        |   `-- berryamin
        `-- docker-pass-initialized-check

但当我启动映像构建时，该过程失败了：

有人能帮忙解释一下这里缺少什么吗？

我们在努力推动ghcr时遇到了这个问题。io我们遇到了这个错误，按照这里的步骤解决了这个错误，让我们推一下https://docs.github.com/en/free-pro-team@最新/软件包/github容器注册表入门/启用改进的容器支持

试着先下载docker镜像并运行build image命令，这对我很有效
