问题会阻止更新或安装新软件
现在已经过了一个星期，每当我运行sudo apt-get update时它会向我显示：

They have been ignored, or old ones used instead. and when i try to download and install a software from terminal it tells me: E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? 我也试过从Synaptic安装软件它也给我同样的错误..我的屏幕右上方还有一个红色三角形告诉我：
更新信息已过时。 这可能是由网络问题或不再存在的存储库引起的，
现在我在网上搜索了很多试图解决这个问题，所以我运行了大量的存储库，看看它们是否有效..但是没有它们工作..
我检查了我的软件来源，我在“其他软件”选项卡上勾选或取消了所有内容，但仍然没有改变。
这就是我现在的软件来源： 
这也是我的etc / apt / source.list的主体：

任何想法我怎么能解决这个问题？
apt似乎使用自己的计算机作为镜像（ 127.0.0.1:9666 ）。 你有没有像apt-cacher这样的软件并删除/禁用它？
如果是这种情况，则应在/etc/apt/apt.conf或/etc/apt/apt.conf中的任何文件中配置该信息。 要查看是否在任何这些文件中设置了它，请使用：
cat /etc/apt/apt.conf grep -r proxy /etc/apt/apt.conf.d/
如果您看到有关这些文件的代理的任何信息，只需使用sudo gedit 编辑，然后使用“＃”对该部分进行注释。 要弄清楚你应该看什么，看看这个答案。
在此之后只需要进行sudo apt-get update修复。 如果没有，那么你将不得不检查为什么它使用localhost作为镜像（你连接到代理吗？）。
