[问题]apt-get中认证的问题

[jswanli]

我使用apt-get install kubuntu-desktop来安装kde桌面，结果出现大量无法通过验证的软件包，请问我应该怎么作？出错如下：

由于出现了太多错误，处理过程被终止了。
E: Sub-process /usr/bin/dpkg returned an error code (1)

以前我也碰到过这种问题，那是我安装kdevelop3的时候，无法通过验证，我只好使用dpkg -i --force bad-verify kdevelop*来安装，可是这次的包实在是太多了。
还有，通过上述命令安装的包，就没办法使用apt-get -f install来删除因为依赖关系而无法运行的包了，是否只能用dpkg -p （或者-r）来卸载？

kde在ubuntu中的包叫“kubuntu-desktop”？？
我是个ubuntu新手，见笑了

[oneleaf]

apt-get clean
然后删除所有非官方的源。
再次安装 kubuntu-desktop

[jswanli]

源里面我按照Ubuntu中文官方网站上“快速设置指南”中推荐的写的，如下：
deb http://ubuntu.cn99.com/ubuntu/ breezy main restricted universe multiverse
deb http://ubuntu.cn99.com/ubuntu/ breezy-updates main restricted universe multiverse
deb http://ubuntu.cn99.com/ubuntu/ breezy-security main restricted universe multiverse
deb http://ubuntu.cn99.com/ubuntu/ breezy-backports main restricted universe multiverse
deb http://ubuntu.cn99.com/ubuntu-cn/ breezy main restricted universe multiverse
deb http://ubuntu.cn99.com/backports/ breezy-extras main restricted universe multiverse
这个不算官方的吗？

从网上找到一个解决的方法，根据《Debian 安全手册 第 7 章 - Debian 的安全机制》中提到的“在/etc/dpkg/dpkg.cfg 引入 "no-debsig"”，然后就可以不验证的去直接apt-get了，不过及其危险，所以平时大家还是尽量让它去验证好了。
该文网址为：

我们只需要
sudo gedit /etc/dpkg/dpkg.cfg
然后在最后面加入no-debsig
然后再apt-get，一切OK

回3楼：kubuntu-desktop是ubuntu下的kubuntu桌面，实际上也算是kde了
