Describe the bug and the command you saw an issue with

I am trying to install cf8-cli from the apt repository:

FROM "node:24.21.0-trixie-slim"

RUN apt-get update \
    && apt-get install -y --no-install-recommends curl ca-certificates gnupg \
    && curl --silent --location https://packages.cloudfoundry.org/debian/cli.cloudfoundry.org.key \
    | gpg --dearmor -o /etc/apt/trusted.gpg.d/cloudfoundry-cli.gpg \
    && echo "deb https://packages.cloudfoundry.org/debian stable main" | tee /etc/apt/sources.list.d/cloudfoundry-cli.list \
    && apt-get update \
    && apt-get install --no-install-recommends --assume-yes cf8-cli \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*

What happened

#7 2.099   Sub-process /usr/bin/sqv returned an error code (1), error message is: Signing key on C19C04748BF33B2E17863557172B5989FCD21EF8 is bad:            The primary key is not live   because: Expired on 2020-09-12T18:17:33Z
#7 3.001 Reading package lists...
#7 3.834 W: OpenPGP signature verification failed: https://cf-cli-debian-repo.s3.amazonaws.com/ stable InRelease: Sub-process /usr/bin/sqv returned an error code (1), error message is: Signing key on C19C04748BF33B2E17863557172B5989FCD21EF8 is bad:            The primary key is not live   because: Expired on 2020-09-12T18:17:33Z
#7 3.834 E: The repository 'https://packages.cloudfoundry.org/debian stable InRelease' is not signed.

Expected behavior
I'd expect the signature to be valid so the package can be installed.

Exact Steps To Reproduce
see above

Provide more context

• platform and shell details ( e.g. Mac OS X 10.11 iTerm): Docker (trixie-based), without cache

Seems it's about one year after the last time it expired: #3579

Start with the provided Dockerfile on the Debian trixie-based image and reproduce the failure with apt-get update. Inspect the Cloud Foundry APT repository key and signing metadata involved in the command; done means the repository signature validates and cf8-cli installs successfully without the expired-key error.
