Ubuntu をバージョン 17.04 から 17.10 にアップデートしたところ、ネットワーク ケーブルをネットワーク カードの 1 つに接続すると、ケーブルが接続されていないと表示されます。ルーターを使用しており、ネットワーク カードが 2 枚あり、Realtek 統合カードを使用したいと考えています。
Realtek ドライバーをインストールしましたが、成功しませんでした。どうすればこの問題を解決できますか? 診断に役立つ可能性のある情報を以下に示します。
更新: 有線ネットワーク プロファイルが多数あったため、それらを削除しました。その結果、[設定] -> [ネットワーク] タブで有線セクションが消えました。

答え1
理由は分かりませんが、いくつかの簡単な変更を加えただけで動作するようになりました。
- Realtekネットワークカードドライバを再インストールしました
- /etc/network/interfaces を変更し、enp4s0 と enp4s2 に関連する行を削除しました。これで次のようになります。
# interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback
- コンピュータを再起動しました。
