brew update 오류 (couldn't find remote ref)

토이프로젝트 진행하면서 MongoDB를 로컬환경에 설치하는 와중에 brew update 명령어를 실행했더니 아래와 같이 에러가 발생했습니다.

 

% brew update

==> Updating Homebrew...

fatal: couldn't find remote ref refs/heads/master

Error: Fetching /opt/homebrew/Library/Taps/dart-lang/homebrew-dart failed!

Error: Some taps failed to update!

The following taps can not read their remote branches:

  dart-lang/dart

This is happening because the remote branch was renamed or deleted.

Reset taps to point to the correct remote branches by running `brew tap --repair`

 

에러메시지를 읽어보니 dart-lang/dart 의 원격 브랜치를 읽을 수 없다고하면서 이름이 변경됐거나 삭제되었을테니 brew tap --repair 를 실행하라고 하네요. 그래서 dart-lang/dart 를 타겟으로 주어 실행하니..

 

% brew tap --repair dart-lang/dart

==> dart-lang/dart: changed default branch name from master to main!

 

이렇게 default 브랜치가 master 에서 main 으로 변경됐다고 친절히 알려줍니다.
