问求教Debian9.12.0操作系统如何部署open-falcon服务，具体是前端的部署？

使用Debian9.12.0操作系统，使用的命令apt-get安装redis和mysql（Mariadb），open-falcon后端组件都可以启动。卡在了部署前端时安装依赖。因为没有安装yum，使用

apt-get install python-pip python-virtualenv

apt-get install python-dev

apt-get install ldap-utils

apt-get install libmysqld-dev

这些命令安装时第一个和第四个无法安装，第一个最后下载pip安装virtualenv，最后一个提示有别的包However the following packages replace it:

libmariadbd18 libmariadbd-dev

尝试安装报错

The following packages have unmet dependencies:

libmariadbd-dev : Depends: libmariadbclient-dev (= 10.1.37-0+deb9u1) but it is not going to be installed

那就继续装，然后又报错

The following packages have unmet dependencies:

libmariadbclient-dev : Depends: libmariadbclient18 (= 10.1.37-0+deb9u1) but 10.1.44-0+deb9u1 is to be installed

然后

这是已经安装的意思吧……回过头再去装前面的还是一样的报错…………无解

一直E: Unable to correct problems, you have held broken packages.，求大神看一眼小白~~~~~
