のようなというエラーが出て、Brewが何もできない
解決策
cd /usr/local/
git status
とすると、いろいろおかしくなってるので、
git reset --hard && git clean -df
これで、GitRepoが綺麗になり、brewができるようになった
参考ページ
問題2 brew updateができない
warning: unable to unlink CONTRIBUTING.md: Permission denied
warning: unable to unlink SUPPORTERS.md: Permission denied
fatal: cannot create directory at '.github': Permission denied
Error: Failure while executing: git pull --quiet origin refs/heads/master:refs/remotes/origin/master

warning: unable to unlink SUPPORTERS.md: Permission denied
fatal: cannot create directory at '.github': Permission denied
Error: Failure while executing: git pull --quiet origin refs/heads/master:refs/remotes/origin/master
というエラーがでた
そこでGoogleと、
このページにたどり着く！
そして、グッドボタンが押されてるのを見てみると
sudo chown -R $(whoami):admin /usr/local
cd $(brew --prefix) && git fetch origin && git reset --hard origin/master
してから、
brew update
すればよいと書いてある！
成功！！！
おまけ
brew updateすると、最後に
Error: Could not link caskroom/cask manpages to:
/usr/local/share/man/man1/brew-cask.1
Please delete these files and run `brew tap --repair`.
というのが出ているので、次いでに調べるとQiitaにすでに投稿がある！

こちらを参考にして、一個目の修正を試すと
brew uninstall --force brew-cask; brew update
うまく言った。
