'nmet dependencies' Ubuntu 安装错误
在 Ubuntu 操作系统上安装探针是报错如下：

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
kunagi : Depends: tomcat6 but it is not going to be installed
Recommends: msttcorefonts
Recommends: ttf-dejavu but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
ERROR
Failed to install the Cloud Insight package, sometimes it may be
due to another APT source failing. See the logs above to
determine the cause.
If the cause is unclear, please contact Cloud Insight support.
报错说明：
以上报错说明 Ubuntu 系统内 APT 包源本身冲突，如果不安装更新软件的话这个问题不会表现出来，但在安装 Cloud Insight 探针时第一步执行的 sudo apt-get update，此时系统内如果有服务需要升级版本，就会报出错。
解决方法：
这个问题 Cloud Insight 本身没有问题，所以可以在安装时分布安装，跳过 update 的操作，具体方法如下：
wget http://download.aiops.com/ci_agent/CiAgent_x.x.0-1_amd64.deb (可以自行查看当前版本)
dpkg -i CiAgent_x.x.0-1_amd64.deb
vi /etc/CiAgent/CiAgent.conf （ 修改成自己的 license_key ）
/etc/init.d/CiAgent restart
以上几步即包括删除不需要的软件包，下载当前最近 Cloud Insight 探针（里面包括探针各种依赖包），修改探针配置文件，添加进自己的 license_key ，重启探针，让配置生效，其他之前的一键复制也是运行的这些功能。
