[SOLVED] Broken packages error while installing zookeeper-server

Issue

I am running Ubuntu 14.04 LTS (Trusty) and was trying to install Cloudera Hadoop with Yarn by following this tutorial.

Under the options I choose To add the CDH 5 repository: and customized url for trusty OS. Then I installed Zookeeper but while installing Zookeeper-Server it is giving me following error:

$    sudo apt-get install zookeeper-server
