Il est recommandé de sauvegarder toutes les sources miroir courantes dans le répertoire /etc/apt et nommez-les sous une forme similaire à source.list.aliyun. Copiez-les directement si nécessaire. Remplacez simplement le fichier source.list.
2Méthode de remplacement et source miroir
Ubuntu utilise apt comme outil d'installation de logiciel et sa liste de sources miroir est enregistrée dans le fichier /etc/apt/source.list.
Commencez par copier source.list en tant que sauvegarde source.list.bak, puis modifiez le contenu source.list par la liste source miroir requise.
Une fois la modification terminée, enregistrez le fichier source.list et exécutez :
sudo apt-get update
Ouvrez le terminal d'Ubuntu et saisissez :
maliao@ubuntu:~$ sudo gedit /etc/apt/sources.list
[sudo] maliao 的密码： 输入密码回车即可
Remplacez l'adresse miroir par l'une des adresses suivantes (les adresses source miroir d'Alibaba, NetEase, Tsinghua et de l'Université des sciences et technologies de Chine sont fournies ci-dessous) et enregistrez.
Après avoir remplacé la source, exécutez la commande suivante pour mettre à jour :
sudo apt-get upgrade
