Individually, Emacs seems able to access elpa.gnu and melpa. But
something about the transitive dependency seems to break. I've heard
speculation that this could be a race condition, but that's a bit over
my head.

With (package-install 'spinner), it works.

With (mapc 'package-install '(spinner lsp-java)), it works.

With (package-install 'lsp-java), it installs some dependencies
successfully, then gives the failure at spinner that I shared.

And yes, I've only been able to reproduce in Docker. One the one hand,
maybe this is a failure in how Docker is being set up. On the other
hand, maybe this is a pathological example of some imperfection in
Emacs.

Thank you!

P.S. My usecase for Docker is mostly to have reproducible setup
instructions for local software, or providing minimal broken
examples. I.e., in the previous, I was trying to check on an editing
environment for Java. And rather than nix, Docker seemed more
approachable for collaborating on recipes.
