我是一名大学生，这个错误已经持续了将近一个月。我一开始以为是服务器错误，但现在我很确定这与服务器无关，因为我试过每台服务器，但都没有用。我使用 Ubuntu 18.04 LTS 已经有几个月了，但这个错误直到现在才出现。这是我的输出 sudo apt-get 更新：

我几乎尝试了所有方法，但都无济于事。我没有双启动，我的常用操作系统是 Ubuntu。请帮帮我...
答案1
您需要修复 source.list 并切换到国家/地区的默认存储库镜像，因为它不允许您未经身份验证下载软件包。您需要编辑文件 /etc/apt/source.list
sudo nano /etc/apt/source.list
将内容替换为以下内容
###### Ubuntu Main Repos
deb http://in.archive.ubuntu.com/ubuntu/ bionic main restricted universe multiverse
###### Ubuntu Update Repos
deb http://in.archive.ubuntu.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://in.archive.ubuntu.com/ubuntu/ bionic-updates main restricted universe multiverse
之后你将能够更新和升级系统
sudo apt update && sudo apt upgrade
