如何编辑/恢复“sources.list”文件

我该如何恢复sources.list崩溃的软件，我无法进行任何软件更新。当我单击更新图标时，我没有得到任何响应。我尝试编辑文件，sources.list“vi”编辑器不起作用。我尝试在“软件更新程序”中输入以下行：

deb http://deb.torproject.org/torproject.org trusty main
deb-src http://deb.torproject.org/torproject.org trusty main

如果您能帮助我，我将不胜感激；我不擅长使用终端。

笔记：

默认情况下，你可以在目录中找到该文件的备份，/etc/apt名为 sources.list.save

因此您可以使用它来恢复丢失的。

sudo cp /etc/apt/sources.list.save /etc/apt/sources.list

否则，如果您没有此文件，您可以访问此链接：http://repogen.simplylinux.ch/输入您的信息，您将获得您的定制sources.list文件对于默认的存储库集，您需要启用这些存储库。

该文件的位置是：/etc/apt/source.list

您可以通过发布sudo vi /etc/apt/source.list或sudo nano /etc/apt/source.list（nano 可能对您来说更容易）来编辑它。

如果您想添加上述存储库，您应该在文件底部添加以下几行：

# Tor Project Repositories
deb http://deb.torproject.org/torproject.org trusty main
deb-src http://deb.torproject.org/torproject.org trusty main
