我点击update-manager_1%3a0.87.9_all.deb，报告说有严重依赖关系错误，无法安装。请各位帮忙。

我跟你一样的问题啊？咋办列？

现在8.04的问题好像还蛮多的……

我的也是，都说依赖关系问题--仍未被配置

首先，下载update-manager-core_0.87.10_i386.deb（http://packages.ubuntu.com/hardy/admin/update-manager-core，备用。
然后，打开新立得，它会提示你update-manage包已经broken，占击右键，选择mark for complete removal。
第三步，进入终端或虚拟控制台，键入

安装过程中应该不会提示什么错误。

还是不行 我现在也 遇到了阿

我升级了8.04但是没有遇见大家所说的问题，我估计是由于kernel引起的倚赖关系，所以建议大家升级2.6.24后然后自动会要求你升级到8.04的
