我的是ubuntu12.04，软件中心只能卸载软件不能安装软件！估计没有人遇到过我的这种情况？软件源我用的是网易163的源。手动检查更新的时候会提示下载软件包仓库信息失败。新立得和apt-get都可以安装软件，就是软件中心奇葩。这是什么烂系统？

这个确实奇葩，ubuntu什么都绑定过去了，肯定会出问题。当然，软件烂也并不代表系统烂，这是局部和全局的关系，但绑定之后，关键部位对全局的影响就不一样了，尤其是软件中心这货。
在此，我要声明的是，Ubuntu只是一个发行版，这叫特例，请不要拿Ubuntu来代表Linux，谢谢。
当然，你要解决问题的话，贴出错误提示也是很有必要的，而软件源的问题，你最好还是贴出source.list吧。

软件中心一如既往

上传附件时提示list文件是禁止的

ubuntu有两个东东
一个是软件中心(不过外观挺漂亮的)
一个是操作记录zeitgeist(不喜欢被监视的感觉)

大家帮我分析一下。谢谢。

个人认为，这是 软件中心渣渣
而不是 系统渣渣

果然，连错误提示都省略了。

软件中心里找软件挺方便的，还可以给软件评分
