[laoyang1989]

机器系统是win7，在虚拟机上安装的ubuntu11.04，配置nfs客户端时，出现的问题如下：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
nfs-common : Depends: libgssglue1 but it is not installable
Depends: libnfsidmap2 but it is not installable
Depends: librpcsecgss3 but it is not installable
Depends: portmap (>= 6.0.0-2ubuntu3)
E: Broken packages
求解释。。。

提示说的是不可安装啊，如果要是没安装的话是installed，我也试了安装这几个，安不上！！！
