Hi,
I've compiled and setup the isc dhclient v4.3.5 downloaded from the isc site and everything works fine.

Title:
  dhclient does not renew leases

Status in bind9 package in Ubuntu:
  Fix Released
Status in isc-dhcp package in Ubuntu:
  Fix Released
Status in bind9 source package in Xenial:

Status in isc-dhcp source package in Xenial:
  Fix Released

Bug description:
  Release: Xenial

  I think this only recently started after some bind9 updates triggered a rebuild. When booting dhclient gets started and acquires an IP address, but it does seem to lock up somewhere as it does not renew the lease.
  In my environment I set the lease time to 5 minutes, so I notice such things rather soon. I looked on the dhcp server side but saw any further dhcp messages come in from the client side.
