apt-get 安装无法连接到镜像

在准备安装软件包时尝试运行 apt-get update 时出现以下错误：

chris@chris-X1C6:/etc/apt$ sudo apt-get update

谷歌搜索了一下，发现这似乎最常与代理设置有关。自从我记得上次apt-get update成功运行以来，我已经通过 Firefox 安装了一个代理，但它目前没有激活，即使激活了，我也没有看到任何指定的代理：

chris@chris-X1C6:/etc/apt$ env | grep -i proxy
chris@chris-X1C6:/etc/apt$

我也尝试过将apt-get update代理选项设置为 false，如中所述这个帖子（因为我似乎没有 apt.conf 文件）：

sudo apt-get update -o Acquire::http::Proxy="false"

结果相同。

任何想法可能是什么原因造成的以及如何解决。

software-properties-gtk

选择从主服务器下载。

sudo apt update && sudo apt full-upgrade

我不认为这是一个代理问题。
