18.04でSudo apt-getが機能しない

まず、このエラーに関連する以前の質問をすべて調べましたが、何も機能しませんでした。以下はSudo apt-get updateの私の出力です：

古い投稿の後、sources.listファイル全体を変更することになりました。

残念ながら、問題は大学のネットワークにありました。電話のホットスポットを使用しましたが、うまくいきました。 "驚くばかり"

16.04から18.04へのアップグレードがソースリストを台無しにしているようです。 /etc/apt/sources.listファイルの既存の内容を次の行に置き換えます。競合を避けるため、/etc/apt/sources.list.d/にある既存の他のソースリストをバックアップおよび削除します。

Sudo apt updateを実行します。問題を解決する必要があります。

このコマンドを使用して、ubuntuコードネームを見つけます

lsb_release -a

次に、リポジトリリストを編集し、次を使用してそのコード名のリンクをコメント解除します。

Sudo nano /etc/apt/sources.list

Sudo apt-get updateを確認してください
