出现错误，当我尝试 "sudo apt-get update"

Question

我现在又安装了 Ubuntu 18.04。之后，我尝试了更新和升级命令。升级命令执行得很好。但是，更新命令没有执行并给出了错误输出。您可以在以下位置查看错误：

sudo apt-get update

服务器 tr.archive.ubuntu.com 目前不可用，如果您尝试在浏览器中访问它，您会收到 404 错误。您可以删除 /etc/apt/sources.list 中 archive. 前面的 tr.，您的命令将起作用。

您可以像这样使用文本编辑器（nano 只是一个示例）来完成此操作

sudo nano /etc/apt/sources.list

或者你可以像这样使用 sed

sudo sed -i 's|http://tr.|http://|' /etc/apt/sources.list
