只部分安装了extlinux包，导致包安装和apt更新问题。

Question

我已经运行12.04 x64 LTS桌面一年了，没有任何问题，但最近我做了一些事情--不知道是什么--似乎导致了一个损坏或部分安装的extlinux包。

现在，我运行的大多数apt安装或每日更新要么失败要么部分失败，其错误类似于下面的错误。

我已经尝试过apt-get clean，apt-get autoclean，使用aptitude接口查找损坏的包(没有结果)，并完成部分安装的extlinux的安装(失败与下面的错误)，没有运气。

有谁知道问题可能是什么，以及如何解决？

Answer 1

它是以UNetbootin作为依赖项安装的。只需要UNetbootin临时做一个安装USB，完成后，不需要保留它的安装。

sudo apt-get purge unetbootin修复了它，没有副作用。

Answer 2

我也有过同样的问题。我能够使用以下命令解析它：

apt-get remove --purge extlinux
apt-get install extlinux
apt-get clean && apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y

而且起作用了！也许能帮上忙。谢谢。
