【问题描述】：
我正在尝试将官方 bash 用于 Windows 64 位（ubuntu 14.04）。问题是，当我尝试更新任何软件包或安装新软件包（例如 g++ 等）时，我总是会遇到同样的错误：
root@notebook:~# sudo apt-get install g++
Reading package lists... Done
Building dependency tree
Reading state information... Done
g++ is already the newest version (4:5.3.1-1ubuntu1).
0 to upgrade, 0 to newly install, 0 to remove and 2 not to upgrade.
1 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.
Do you want to continue? [Y/n] Y

qemu-user-binfmt 包脚本错误。首先你需要尝试 cmd：apt-get purge qemu-user-binfmt。如果问题未解决，您需要删除目录 /var/lib/dpkg/info/ 中的文件 qemu-user-binfmt.pre*、qemu-user-binfmt.post*。并运行 apt-get remove qemu-user-binfmt。

@Šerg 谢谢。它有帮助。你能把你的解决方案写成答案吗？我会接受的。
