I'm following this  tutorial to install Linux in a system that does not have CD reader nor USB boot capabilities. Eventually, I reached the point where I had to install isc-dhcp-server and I did, sort of. Apt tells me that there's one partially installed package. I run sudo apt-get install -f and I get the following:Job for isc-dhcp-server.service failed. See 'systemctl status isc-dhcp server.service' and 'journalctl -xn' for details.invoke-rc.d: initscript isc-dhcp-server, action start failed.dpkg: error processing package isc-dhcp-server (--configure):subprocess installed post-installation script returned error exit status 1Errors were encountered while processing:isc-dhcp-serverE: Sub-process /usr/bin/dpkg returned an error code (1)If I do /etc/init.d/isc-dhcp-server start the prompt consists of the first two lines of the same message.Output from sudo systemctl status isc-dhcp-server: isc-dhcp-server.service - LSB: DHCP server   Loaded: loaded (/etc/init.d/isc-dhcp-server)   Active: failed (Result: exit-code) since Fri 2014-12-12 13:19:25 CST;
