Installing opennms-plugin-protocol-dhcp fails

I am having problems installing the opennms-plugin-protocol-dhcp plugin.  I get a package error.  Maybe I'm not doing something right or the package is missing?  When I install the package, I get the following error:

sudo apt install opennms-plugin-protocol-dhcp
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package opennms-plugin-protocol-dhcp is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
opennms-common

E: Package 'opennms-plugin-protocol-dhcp' has no installation candidate
