關於 APT 安裝套件發生的問題~~~

[Lost-Angel]

請教一下各位前輩們，小生的系統是 Debian Unstable ，以下是小生嘗試執行 apt-get install kde-core 安裝 KDE 桌面環境之時所發生的錯誤，請教一下各位前輩們這到底是怎麼一回事呢??? 到底該怎麼解決才好呢??? 煩請各位前輩指點一下不才的小生好嗎??? 非常的感謝各位!!!

Reading package lists...
Building dependency tree...
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.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
kde-core: Depends: kdebase but it is not going to be installed
E: Broken packages

小弟亂亂猜: 可以用 aptitude 看看有沒有沒unmet 的 dep.

感謝前輩指點，小生對 aptitude 不熟，可否煩請稍加說明一下。
小生實在不懂，apt 不是都會自行解決套件相依的問題嗎??? 為什麼還會出現這樣子的套件相依問題呢??? 可否煩請前輩們再度指點一下不才的小生好嗎??? 非常的感謝各為!!!

因為有 broken package 的關係.. 打開 aptitude 按 U 再按 b 就會發現有紅色的字... 這是因為相依性不可能滿足
我猜應該是 libspell 吧... 最近 unstable 很刺激喔.. 遇到這種情形就多等幾天吧

這裡不是有答案嗎?
