我要下載ghc6。但是，當我輸入
sudo apt-get install ghc6
sudo apt-get -f install ghc6
sudo apt-get install --reinstal ghc6
它給出了同樣的錯誤：
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:
ghc6: Depends: libgmp3-dev but it is not installable
Depends: libffi-dev but it is not installable
Depends: libbsd-dev but it is not installable
E: Broken packages
我該如何解決這個問題或如何將 ghc6 安裝到我的桌面上
