Homebrew Update 시 오류

일정 주기마다 brew update를 실행하고 cleanup 이랑 upgrade를 하는데 아래와 같은 오류가 발생

brew update && brew upgrade && brew cleanup

...

Error: Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask failed!
Updated 4 taps (homebrew/cask-versions, homebrew/cask-fonts, homebrew/core and homebrew/cask).

brew doctor 실행

working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: You have the following deprecated, official taps tapped:
  Homebrew/homebrew-cask-drivers
Untap them with `brew untap`.

Warning: You have an unnecessary local Cask tap.
This can cause problems installing up-to-date casks.
Please remove it by running:
  brew untap homebrew/cask

Warning: You have an unnecessary local Core tap!
This can cause problems installing up-to-date formulae.
Please remove it by running:
 brew untap homebrew/core

하라는 대로 함.

Homebrew/homebrew-cask-drivers와 homebrew/cask, homebrew/core를 remove 하라고 하는 것 같아서 실행.

차례대로 실행
brew untap Homebrew/homebrew-cask-drivers

brew untap homebrew/core

brew untap homebrew/cask

 

정상 작동.

 

homebrew/cask-drivers was deprecated. This tap is now empty and all its contents were either deleted or migrated.

 

deprecated되고 삭제되거나 마이그레이션된다고 한다.
