未满足的依赖项

Question

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：

Unpacking collada-dom2.4-sp-dev (2.4.4.1-ubuntu1~trusty1) ...

Answer 1

将 sources.list.d 放在一边似乎是一个可能不理想的修复，实际上可能无法解决根本问题。特别是如果那里有您真正想要保留的资源。我认为这是更好的答案：dpkg 错误：“试图覆盖文件，这也在......”

对于这个特定的问题，我使用了：

sudo dpkg -i --force-overwrite /var/cache/apt/archives/collada-dom2.4-sp-dev_2.4.4.1-ubuntu1~trusty1_amd64.deb

注意：您需要将 .deb 文件替换为您的系统抱怨的文件。仍然不知道是什么导致了今天更新的这个问题......？

Answer 2

我解决了这个问题。显然，我有第三方存储库导致了问题。我用以下命令删除了它们：

sudo mv /etc/apt/sources.list.d/ /etc/apt/sources.list.d.bk/
sudo mkdir /etc/apt/sources.list.d/

然后我跑了sudo apt-get install -f
