这是在kubuntu时，不知道怎么搞的，进入adept-manager时出现这个
The APT Database could not be opened! This may be caused by incorrect APT configuration or some similar problem. Try running apt-setup and apt-get update in terminal and see if it helps to resolve the problem.
求教大侠们。
还有一个，不能用gedit修改sourceslist。后来想改用kate修改，可是又无法保存。求教

同志们，帮帮忙吧。现在没法升级啊，也没办法看rmvb，啊

是不是你的sources.list文件的问题,提示执行update那就来一下了看看有什么出错信息啊
