homebrewのインストールが上手く行きません。

Question

wgetを使いたいため、homebrewのインストールをしたいです。
macOSで、以下を入力しインストールを試みました。

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

しかし、結果は以下です。
==> Checking for sudo access (which may request your password)...
Password:
==> This script will install:
/usr/local/bin/brew
/usr/local/share/doc/homebrew
/usr/local/share/man/man1/brew.1
/usr/local/share/zsh/site-functions/_brew
/usr/local/etc/bash_completion.d/brew
/usr/local/Homebrew

Press RETURN/ENTER to continue or any other key to abort:
==> /usr/bin/sudo /usr/sbin/chown -R taku:admin /usr/local/Homebrew
==> Downloading and installing Homebrew...

fatal: ambiguous argument 'refs/remotes/origin/master': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

全く同じ質問内容の投稿で、

git -C $(brew --repository homebrew/core) checkout master

以上のコードを実行することで解決したようなのですが、これを実行したところ以下のようなエラーが起きてしまいます。
error: pathspec 'master' did not match any file(s) known to git

brew doctor

の実行内容は以下の通りです。
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: A newer Command Line Tools release is available.
Update them from Software Update in System Preferences or run:
softwareupdate --all --install --force

If that doesn't show you any updates, run:
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install

Alternatively, manually download them from:
https://developer.apple.com/download/all/.
You should download the Command Line Tools for Xcode 13.2.1.

Warning: Homebrew/homebrew-core was not tapped properly! Run:
rm -rf "/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core"
brew tap homebrew/core

Warning: "config" scripts exist outside your system or Homebrew directories.
./configure scripts often look for *-config scripts to determine if
software packages are installed, and which additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
/Library/Frameworks/Python.framework/Versions/3.9/bin/python3.9-config
/Library/Frameworks/Python.framework/Versions/3.9/bin/python3-config
/opt/anaconda3/bin/icu-config
/opt/anaconda3/bin/krb5-config
/opt/anaconda3/bin/freetype-config
/opt/anaconda3/bin/xslt-config
/opt/anaconda3/bin/libpng16-config
/opt/anaconda3/bin/python3.7-config
/opt/anaconda3/bin/libpng-config
/opt/anaconda3/bin/xml2-config
/opt/anaconda3/bin/python3.7m-config
/opt/anaconda3/bin/python3-config
/opt/anaconda3/bin/curl-config
/opt/anaconda3/bin/ncursesw6-config
/opt/anaconda3/bin/pcre-config

Warning: Some taps are not on the default git origin branch and may not receive
updates. If this is a surprise to you, check out the default branch with:
git -C $(brew --repo homebrew/core) checkout

初心者で申しございません。

Homebrew インストール時に homebrew-core という git リポジトリをクローンする処理が行われますが、たまに失敗するようで、teratail でもよく質問されてます。
とりあえず brew doctor の指示通り
rm -rf "/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core"
brew tap homebrew/core
すると良いかも。(怖いコマンドですが…。)
