A build is hanging or taking a very long time after disabling the Bitrise Homebrew mirror on the stack.
If you need to disable to Bitrise Homebrew mirror for any reason (for example, it might be necessary in order to fetch the latest version of a tool), we recommend setting the HOMEBREW_NO_INSTALLED_DEPENDENTS_CHECK Env Var to 1. If set, Homebrew does not check for broken linkage of dependents or outdated dependents after installing, upgrading or reinstalling formulae.
