使用には問題は発生していないのですが，気持ちが悪く，修復したいと思っております．
ご教示いただけますと幸いです．

/Users/user_name/.oh-my-zsh/tools/check_for_upgrade.shのファイルが壊れているようですね。

正しいファイルで置き換えましょう。

エラー発見行の手前の、関数 update_ohmyzsh の中身がぐちゃぐちゃです。

github を参考に関数内を以下のように書き直したのですが，更なるエラーが出てしまいます．
どのように対応したら良いかご教示いただけますと幸いです．
```
function update_ohmyzsh() {
if ZSH="$ZSH" zsh -f "$ZSH/tools/upgrade.sh" --interactive; then
update_last_updated_file
fi
}
```

There was an error updating. Try again later?
