   E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

我认为我必须对包含有关服务器和源的信息的文件进行一些更改？你能告诉我如何解决这个问题吗？

当我尝试过

    sudo apt-get update

它起作用了。我认为它有效，因为它是空的？

更新

我试过答案 here这是我得到的更新输出。

  Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  Package build-essential is not available, but is referred to by another package.
  This may mean that the package is missing, has been obsoleted, or
  is only available from another source

  E: Package 'build-essential' has no installation candidate

请问这里有什么指点吗？

Answer 1

明白了。

首先按照here的解决方案

然后运行

    sudo apt-get update

干净!
