我已经运行 12.04 x64 LTS 桌面大约一年了，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 extlinux 包损坏或部分安装。
现在，我运行的大多数 apt 安装或日常更新都会失败或部分失败，并出现类似以下的错误。
我尝试过apt-get clean，，apt-get autoclean使用 aptitude ncurses 界面来查找损坏的软件包（没有结果）并完成部分安装的 extlinux 的安装（失败并出现以下错误），但没有成功。
有人知道可能是什么问题以及如何解决它吗？

答案1
它被安装联合国网启动作为依赖项。仅需要 UNetbootin 临时制作安装 USB，完成后无需保留其安装。
sudo apt-get purge unetbootin已修复，没有副作用。
答案2
我也遇到了同样的问题。我可以使用以下命令解决此问题：
apt-get remove --purge extlinux
apt-get install extlinux
apt-get clean && apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y
确实有效！可能对某些人有帮助。谢谢。
