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

这里可能是什么问题？我该如何解决？

Answer 1

尝试使用

sudo apt-get update

然后重试。

Answer 2

如果sudo apt-get update也不起作用，请按照以下步骤操作：-

1. 打开/etc/apt/sources.list文件。
2. 检字后http://security.ubuntu.com/ubuntu/中sources.list的文件，让这个词是xyz
3. 转到地址http://security.ubuntu.com/ubuntu/，然后单击 diss。现在检查xyz此路径中是否存在。如果不存在，则替换xyz为“dists”中存在的元素，例如：- saucy、lucid、trusty 等。
4. 现在运行sudo apt-get update命令。
