`Chef`で`Ubuntu`の multiverse
リポジトリを有効にするために以下のレシピを書きました。これで無効状態から有効に変えることはできたのですが、二度目以降がエラーになってしまいます。

```

    execute "enable multiverse" do
        command %Q{ grep -q '^# deb.*multiverse' /etc/apt/sources.list && sed -i '/^# deb.*multiverse/ s/^# //' /etc/apt/sources.list && apt-get update }
        ignore_failure true
    end
    
```

以下が該当部分のエラーメッセージです。

```

`ignore_failure true`を設定してるので`grep`が失敗を返してもレシピ自体は正常終了すると思ったのですが、そうではないのでしょうか？
