我运行时遇到错误apt-get upgrade。我似乎安装了一个具有未满足的依赖项的软件包。
uname -a输出：

这是以下的输出apt-get upgrade：

我对包管理器的了解apt非常有限，并且我对更多信息的搜索没有发现任何对处理此问题有用的信息。
我还尝试了一些常见的解决方案来修复未满足的依赖关系（例如apt-get clean并尝试再次升级）。如果特定的解决方案不明显，那么对其中一些命令的输出含义的更多了解将非常感激。

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libefl-bin : Depends: libefl (= 201604022131-32022~ubuntu14.04.1) but it is not going to be installed
libelementary : Depends: libefl but it is not going to be installed

答案1
我在你发布后几分钟内就找到了这个帖子。看来这个问题是最近几天才出现的，并且与术语包有关。
我或多或少遵循了这些说明，以便再次正常工作：http://ubuntuforums.org/showthread.php?t=2319182
由于清除了 libefl，我无法完全遵循它们，因此我首先使用 dpkg 删除术语，然后使用 libelementary，并重新安装 libefl。之后，apt又高兴了。
答案2
对我来说，通过工作强制安装dpkg：
sudo dpkg --force-all -i /var/cache/apt/archives/libefl_201604022131-32022~ubuntu14.04.1_amd64.deb
在那之后：
sudo apt-get -f install
答案3
我的有点不同。我必须做：
sudo dpkg -r libelementary
sudo apt-get purge terminology
sudo apt-get autoremove
重启机器
sudo apt-get install terminology
然后：
sudo dpkg --force-all -i /var/cache/apt/archives/libefl-bin_201604032132-32025~ubuntu14.04.1_amd64.deb
答案4
我有一个类似的问题：
dpkg: dependency problems prevent removal of libefl:
evas-loaders depends on libefl.
dpkg: error processing package libefl (--remove):
dependency problems - not removing
Errors were encountered while processing:
libefl
禁用启蒙 PPA 为我解决了这个问题。
