This may mean that you haverequested an impossible situation or if you are using the unstabledistribution that some required packages have not yet been createdor been moved out of Incoming.The following information may help to resolve the situation:The following packages have unmet dependencies: libssl-dev: Depends: libssl0.9.8 ( 0.9.8k-7ubuntu8) but 0.9.8k-7ubuntu8.5 is to be installed 这个时候应该请令一个工具出马了aptitude 使用这个工具当某个库依赖的库与当前版本不一致时aptitude 会尝试降级当前这个库的版本同时解决降级这个库对其它软件的依赖性的影响 最终成功安装apt-get 没法安装的软件
如#aptitude install vim-gnome
