package isc-dhcp-server 4.1.ESV-R4-0ubuntu5.8 [modified: usr/sbin/dhcpd] failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

I made some editing on terminal to reset or reconfigure this package initialization in order to enable the wifi sharing as infrastructure type. But while i did that and got this problem always with a system problem detected notification.

And after a while i lost all my eth interfaces . then i repaired the system during boot and got a result but the eth2 became eth3 .
