![etc/apt/sources.list 存在问题](https://linux22.com/image/1086361/etc%2Fapt%2Fsources.list%20%E5%AD%98%E5%9C%A8%E9%97%AE%E9%A2%98%20.png)
我是 ubuntu 新手,打开 sources.list 时意外创建了几个文档。例如,我有 sources.list、list 和无标题文档。我认为我的计算机现在无法知道它引用的是哪个文档,我在尝试下载 R 时遇到错误。您知道如何修复这个问题吗,这样我就只有一个名为 sources.list 的文档,里面有一个镜像可以下载软件包?

如果你的 sources.list 文件损坏了。你可以尝试以下操作:
删除损坏的文件:
sudo rm /etc/apt/sources.list
sudo software-properties-gtk
然后勾选所有框,并更改“从...下载”服务器,这将创建一个新的 sources.list。
然后根据需要添加任何额外的存储库。
这对我有用。
