This has started working again for us recently. We can now again (at least for the moment) install jq using the built-in homebrew installation in Xcode Cloud. Build are running on latest realease, which at the moment is macOS 12.6 and Xcode 14.0.1. We have switched back to using the built-in homebrew, shaving ~3 minutes of each of our builds, but we are ready if it stops working again ;-)

We have the same problem. Most of our workflows stopped working, because homebrew can no longer install certain casks. Our CI is essentially down. Symptom A: Installation, e.g. of brew install jq, fails: $ brew install jq ==> Installing jq dependency: oniguruma ==> Pouring oniguruma--6.9.8.monterey.bottle.tar.gz Error: The `brew link` step did not complete successfully The formula built, but is not symlinked into /usr/local Could not symlink include/oniggnu.h /usr/local/include is not writable. Symptom B: running brew doctor lists multiple missing directories: $ brew doctor Warning: The following directories do not exist: /usr/local/Frameworks /usr/local/include /usr/local/lib /usr/local/sbin /usr/local/var/homebrew/linked Anecdotally, brew install swiftlint does not have the same problem. Any ideas?
