应用错误收集

我想使用Docker BuidlKit的一项实验性功能（mount = type = cache）

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设置了密码存储区，成功登录到docker中心，在PATH中使用“ docker-credential-pass”二进制文件，设置了“使用加密密码的docker登录过程”。（如

中所述

"How to Enable Docker Experimental Features and Encrypt Your Login Credentials"

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

但是当我启动映像构建时，该过程失败并显示：

有人可以帮忙解释一下这里缺少什么吗？

前端xxx无法解决：rpc错误：代码=未知desc =（...）退出：`退出状态2：gpg：解密失败：无密钥`
