build copy-from: Unmounting, invalid argument, no stage or image found with that name

[edsantiago]

It's a one-off, but I don't like one-offs:

@flouthoc do you have time to look at this?

[flouthoc]

@rhatdan Sure. I'll take a look at this thanks.

I am unable to reproduce this race no matter how many times i invoke this build. I can imaging a scenario where this happens when quay.io/libpod/testimage:20210610 is removed forcefully from storage while the build is in progress but I am not sure if that can happen in CI.

My reproducer attempt ( from which i am not able to reproduce )

FROM quay.io/libpod/testimage:20210610 AS test
RUN rm -f /etc/alpine-release
FROM quay.io/libpod/alpine AS final
COPY --from=quay.io/libpod/testimage:20210610 /etc/alpine-release /test/

podman build --no-cache --jobs 4 -t test .

Since I am unable to reproduce this on main and it had only occurred once with no history, I am closing this issue but @edsantiago please reopen the issue if this is a constant issue or there are more occurrence of this but as of now I can't reproduce this from main.
