由于libxml-simple-perl无法安装快门
我无法安装快门：

Ubuntu版本是12.04 LTS – “Wubuntu”标准安装。 我没有添加任何其他存储库。
运行： apt-cache policy shutter libxml-simple-perl libxml-sax-perl libxml-libxml-perl libxml-sax-expat-perl导致：
Installed: (none) and 500 http://archive.ubuntu.com/ubuntu/ precise/main amd64 Packages
对于每个包。
接下来做什么？
将镜像添加到我的源配置后：
-
sudo apt-get update -
sudo apt-get install -f
和快门安装。
