Failed to solve with frontend xxx: rpc error: code = Unknown desc = (...) out: `exit status 2: gpg: decryption failed: No secret key`

I'd like to use one experimental feature of Docker BuidlKit (mount=type=cache)

The first lines of my Dockerfile are:

    # 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

I have setup a Password Store for docker, logged in successfully to docker hub, "docker-credential-pass" binary in my PATH, setup the "docker login process using the encrypted password". (as described in

"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

But when I launch the image build, the process fails:

May someone help to explain what's missing here?
