Q: Is there a way to get a buggy package to work on debian stretch? I need to install isc-dhcp-server on debian stretch, but the package cannot be installed correctly.
apt-listbugs list isc-dhcp-server:
 #867362 - isc-dhcp-server: DHCP server does not start after upgrade to Stretch

After installing the package 
# systemctl status isc-dhcp-server

Installing the package from source (4.3.6 version) cannot solve the problem, Is there a way to install isc-dhcp-server on debian stretch?

A: I have been using the official ISC DHCPd Debian packages in Stretch without systemd, and been using it in Debian and upgrading that particular DHCP cluster since Debian 6 without many hitches.
As for Stretch, I have been using isc-dhcp on it for over a year, I think, since I migrated earlier to take advantage of new versions, instead of assembling a deb of my own. (I had some reasons related to Windows DHCP clients)
As normally those kind of services should be alone in a machine, I suggest making an exception and have a Debian server with the sysV init utilities.
For that, you can do:
sudo apt-get install  sysvinit-core sysvinit
