不能'；t在bash for windows中更新和下载任何软件包

我正在尝试使用官方的bash for 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，总是会出现相同的错误：

root@notebook:~# sudo apt-get install g++
Reading package lists... Done

g++ is already the newest version (4:5.3.1-1ubuntu1).

包qemu用户binfmt的脚本错误

首先，您需要尝试cmd：

apt-get purge qemu-user-binfmt

若问题未解决，则需要删除dir/var/lib/dpkg/info/中的文件：

qemu-user-binfmt.pre*
qemu-user-binfmt.post*

跑

apt-get remove qemu-user-binfmt
