在更新 Ubuntu 14.04 时，我遇到了以下错误消息：
The following packages have unmet dependencies:
collada-dom-dev : Depends: collada-dom2.4-sp-dev but it is not installed
collada-dom2.4-sp : Depends: collada-dom2.4-sp-dev but it is not installed
E: Unmet dependencies. Try using -f.
任何帮助将不胜感激。
编辑：
在安装丢失的包失败后，使用：
sudo apt-get -f install
我收到这条消息：
