I have installed Isc-dhcp-server and configured the files accordingly still it is showing the error that its not configured to listen to any interfaces. i have ubuntu 17.04 64 bit

Interface file :

auto lo
iface lo inet loopback
iface enp2s0 inet static
address 10.90.90.5
netmask 255.255.255.0
gateway 10.90.90.1
broadcast 10.90.90.255
dns-nameservers 8.8.8.8
up service isc-dhcp-server restart

in /etc/default/isc-dhcp-server file

   INTERFACES="enp2s0"

/etc/dhcp/dhcpd.conf file:

 subnet 10.90.90.0 netmask 255.255.255.0 {
      range 10.90.90.10 10.90.90.20;
      default-lease-time 600;
      max-lease-time 7200;
      option routers 10.90.90.1;
    }

A bit late but :

isc-dhcp-server as configuration file in /etc/default folder named isc-dhcp-server is this file at the very last line you must set the interface wich isc-dhcp-server will listen :

# On what interfaces should the DHCP server (dhcpd) serve DHCP requests?
#       Separate multiple interfaces with spaces, e.g. "eth0 eth1".
INTERFACESv4="eth0 eth1"
INTERFACESv6=""

Try with INTERFACESv4 key.

Then restart the server.

server isc-dhcp-server restart

Well it seems like your interface enp2s0 isn't up. You can check this by using ifconfig.

You can fix it by putting: auto enp2s0 under auto lo in /etc/network/interfaces

The problem was my isc-dhcp-server configuration file was getting reset to original file with blank interfaces. I did re-installation of ubuntu and it worked all well.
