bash - 无法在 bash for windows 中更新和下载任何包

Question

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，我总是会遇到相同的错误:

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.

E: Sub-process /usr/bin/dpkg returned an error code (1)

Answer 1

包 qemu-user-binfmt 的错误脚本。

首先你需要尝试cmd:

apt-get purge qemu-user-binfmt

如果问题没有解决，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
