evince 的权限问题，用sudo evince 试试呢
软件中心很难用，一般建议用synaptic吧

pyexpat.x86_64-linux-gnu.so和libexpat.so.1坏了，先说你乱改了些啥东西

谢谢，我的是ubantu14.04系统 最近
1.按照网上方法http://www.iteye.com/topic/1134519安装oracle失败了 按步骤装了好多包添加了一些环境变量
2.装了个深度音乐播放器和百度插件
别的好像没什么操作了，请问是这个导致的么，如何解决呢

果然是按照网上那些乱七八糟的教程搞的。为了安装一个过时的ia32-libs，就去混用旧源，不出问题才怪。
先把源列表里raring相关的东西删了，再用sudo apt-get update刷新一下包列表
用aptitude search '~o'来查找源里不存在的包，升级或删掉
