我刚刚安装了 Ubuntu 14.04 (trusty) 进行测试运行，因为我需要使用 monodevelop，所以我决定也安装它。之前我在 12.04 上花了很大力气从头编译 monodevelop。这次我想如果我能用简单的方法 PPA 来完成就好了。
所以我补充道ppa:雇主/monodevelop并尝试过：
$ sudo apt-get install monodevelop-current

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:
monodevelop-current : Depends: monodevelop-4.0 (= 4.2.2-1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
我对 PPA 还比较陌生，所以我不确定我是否做错了什么，或者 monodevelop + 14.04 是否存在问题？

看起来存储库出了点问题。现在，一周过去了，这个问题已经解决了，我无需做任何新的事情。
