Connexion refusée pendant qu'apt-get met à jour ubuntu 18.04 via un proxy
J'ai récemment installé Ubuntu 18.04 et je voulais installer sublime. J'ai essayé de lancer Sudo apt-get update auparavant et j'ai le résultat suivant

Je suis connecté via un proxy et Internet fonctionne correctement sur le navigateur. J'ai aussi essayé le suivant:

Notez que apt-get update fonctionne correctement sans proxy sur mon hotspot mobile, mais pas via le proxy sur mon réseau local/wifi. Comment puis-je réparer ça ?

Les suivants fonctionnent comme un charme:
Ajouter ceci dans le fichier ~/.bashrc
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'
puis lancez ce qui suit dans votre terminal:
source ~/.bashrc
pour actualiser le terminal et,
iiitproxy
Je ne suis pas trop sûr de ce qui est différent ici, mais cela a fonctionné
Le problème est que les paramètres de proxy ne sont pas transmis au niveau "Sudo". Vous pouvez faire un ping-et-wget en tant qu’utilisateur normal puisque les paramètres http_proxy et https_proxy sont définis pour cet utilisateur actuel. Lorsque vous utilisez Sudo, ces variables d'environnement ne sont pas transmises à l'utilisateur avec privilèges.
La solution consiste à utiliser -E avec Sudo pour transmettre ces variables d’environnement à l’utilisateur élevé.
Par exemple, procédez comme suit:
Sudo -E apt-get update
Ça devrait marcher.
Pour 18.04, créez un nouveau fichier dans /etc/apt/apt.conf.d/proxy.conf
Ecrivez vos paramètres de proxy dans ce fichier, par exemple:
Acquire :: http :: Proxy " http: // utilisateur: [email protected]: port / "; Acquire :: https :: Proxy " http: // utilisateur: [email protected]: port / ";
et il fonctionne.
