Error: Failed to get curl path

I was upgrading my packages

Start with the brew upgrade invocation and the handling of the brew_exit_non_zero error; the report names no source file or test. Reproduce with Homebrew 6.0.17 and the reported package set, then trace the Failed to get curl path failure. Done means the upgrade-all failure is handled as intended and verified with an appropriate test.
