Public bug reported: It seems that this is a variation of this same bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=807707
Deployed a new Ubuntu 16.04 LTS image on Microsoft Azure: DISTRIB_ID=Ubuntu DISTRIB_RELEASE=16.04 DISTRIB_CODENAME=xenial DISTRIB_DESCRIPTION="Ubuntu 16.04.1 LTS" NAME="Ubuntu" VERSION="16.04.1 LTS (Xenial Xerus)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 16.04.1 LTS" VERSION_ID="16.04" HOME_URL="http://www.ubuntu.com/"; SUPPORT_URL="http://help.ubuntu.com/"; BUG_REPORT_URL="http://bugs.launchpad.net/ubuntu/"; VERSION_CODENAME=xenial UBUNTU_CODENAME=xenial Kernel: 4.4.0-62-generic Installed ddclient: 3.8.2-2ubuntu2 After ddclient is installed and running, you can see its exit-hook script under /etc/dhcp/dhclient-exit-hooks.d #!/bin/sh # /etc/dhcp/dhclient-exit-hooks.d/ddclient - exit hook for dhclient [ -x /usr/sbin/ddclient ] || exit 0 [ -f /etc/default/ddclient ] || exit 0 . /etc/default/ddclient [ $run_dhclient = "true" ] || exit 0 case $reason in BOUND | RENEW | REBIND) /usr/bin/logger -t dhclient $reason, updating IP address with ddclient /usr/sbin/ddclient -daemon=0 -syslog > /dev/null 2>&1 ;; *) ;; esac If you reboot , the VM won't come back again with issues getting route/gateway info from DHCP server. It seems like, changing the script to the one below, fixes the issue: #!/bin/sh # /etc/dhcp/dhclient-exit-hooks.d/ddclient - exit hook for dhclient [ -x /usr/sbin/ddclient ] || return [ -f /etc/default/ddclient ] || return . /etc/default/ddclient [ $run_dhclient = "true" ] || return case $reason in BOUND | RENEW | REBIND) /usr/bin/logger -t dhclient $reason, updating IP address with ddclient /usr/sbin/ddclient -daemon=0 -syslog > /dev/null 2>&1 ;; *) ;; esac Somehow the reported version on Debian to have a fix is 3.8.2-2 (which is the same) but maybe the patch didn't get through?
