I tried several times to submit to forums to obtain assistance but repeatedly kept getting rejected.  Hoping to have better luck here. 

Will the agent only work on the stable version of ubuntu or is there a way around this issue? 

Steps to reproduce:

root@server:~# apt install zabbix-agent -y

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:
 zabbix-agent : Depends: libldap-2.4-2 (>= 2.4.7) but it is not installable
