我有一台旧的 Debian 拉伸机，并且我一直面临着 apt 源列表的一些问题。我发现了一些与我的问题相关的问题（例如这个），但是它们不太适合我。
我的源列表中有几个存储库无法更新。为了隔离问题，我对它们全部进行了评论，只留下了deb http://deb.debian.org/debian/ stretch main：
# Debian Stretch, dépôt principal
deb http://deb.debian.org/debian/ stretch main
# Debian Stretch, mises à jour de sécurité
#deb http://security.debian.org/ stretch/updates main
# Debian Stretch, mises à jour "volatiles"
#deb http://deb.debian.org/debian/ stretch/updates main
#deb http://archive.debian.org/debian jessie-backports main
当我尝试时，apt-get update我得到的是：
# apt-get update

您知道可能是什么问题以及我该如何解决它吗？
谢谢 ：）

感谢@user4089，我发现了一个错误的代理配置，现在 apt 工作正常。
我刚刚注释掉了来自 Acquire::http::Proxy "http://XXX.XXX.XXX.XXX:XXX"的行apt.conf。
