可能是服务器问题 - 无法 apt-get 更新

当我跑步时：

sudo apt-get update

我最后收到这个错误：

W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/Release  Unable to find expected entry 'restricted/source/Sources' in Release file (Wrong sources.list entry or malformed file)

E: Some index files failed to download. They have been ignored, or old ones used instead.

问题如何从我的 sources.list 中删除格式错误的行？类似，但是有错误报告Malformed line 91 in但是这个错误没有显示任何错误的行号。

在过去的两个小时里，我一直在尝试解决这个问题。

  • 确认sources.list没有错误
  • 尝试过这解决方案并得到同样的错误。

最后，几分钟前起作用的是从 Synaptic 中“选择最佳服务器”，最终成功刷新了所有软件包列表。

但我仍然无法安装新软件。这是一个新鲜的安装Ubuntu 14.04.3 64 位来自主页。

当我运行时sudo apt-get install libpq-dev，我收到以下响应：
