apt-getがプロキシ経由でUbuntu 18.04を更新しているときに接続が拒否される

最近、ubuntu 18.04をインストールしましたが、崇高なものをインストールしたかったのです。その前にSudo apt-get updateを実行しようとしても、次の出力が得られます

私はプロキシ経由で接続し、インターネット上でブラウザで正常に動作しています。私も次のことを試しました：

apt-get updateは、モバイルホットスポットでプロキシなしで正常に機能しますが、LAN/WiFiでプロキシを介しては機能しません。どうすれば修正できますか？

魅力として次の作品：

これを〜/ .bashrcファイルに追加します

alias iiitproxy='export http_proxy="http://proxy.iiit.ac.in:8080"; export https_proxy="http://proxy.iiit.ac.in:8080";export ftp_proxy="http://proxy.iiit.ac.in:8080"; echo "Acquire::http::proxy \"http://proxy.iiit.ac.in:8080/\";" | Sudo tee /etc/apt/apt.conf'

次に、ターミナルで次を実行します。

 source ~/.bashrc

ターミナルを更新し、

iiitproxy

ここで何が違うのかはよくわかりませんが、うまくいきました

問題は、プロキシ設定が「Sudo」レベルに渡されていないことです。現在のユーザーにhttp_proxyおよびhttps_proxy設定が設定されているので、通常のユーザーとしてpingとwgetを実行できます。 Sudoを使用すると、これらの環境変数は昇格したユーザーに渡されません。

解決策は、-EをSudoで使用して、これらの環境変数を昇格したユーザーに渡すことです。

たとえば、次のことを行います。

Sudo -E apt-get update

動作するはずです。

18.04では、/ etc/apt/apt.conf.d/proxy.confに新しいファイルを作成します

このファイルにプロキシ設定を書き込みます。次に例を示します。

Acquire :: http :: Proxy " http：// user：[email protected]：port / "; Acquire :: https :: Proxy " http：// user：[email protected]：port / ";

そしてそれは動作します。
