私はLinuxを使用しています。 MacにUbuntuをインストールしたいです。 USBスティックからインストールする方法をインターネットで検索し、このガイドを見つけました。https://tecadmin.net/how-to-create-bootable-linux-usb-using-ubuntu-or-linuxmint/ステップ1の例
$ sudo add-apt-repository ppa:gezakovacs/ppa
$ sudo apt-get update
$ sudo apt-get install unetbootin
だからこの3つのステップを実行しましたが、エラーが発生しました。私はLinuxを数時間しか使っていなかったので、コマンドラインエラーメッセージを解釈するのはうまくいきません。「E：」の後に続くメッセージは何を意味し、この問題を解決するには？
まず、適切なリポジトリを追加します。
