i think this affects more than just "bond" interfaces, and more than just the gateway setting from /etc/network/interfaces. i think dns- settings are also affected as experienced on 4 of my systems. note bug #1628552
-- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ifupdown in Ubuntu. https://bugs.launchpad.net/bugs/1573272 Title: default gateway route not installed for bond interfaces through reboot Status in ifupdown package in Ubuntu: Confirmed Bug description: Expectation: After reboot, route for default gateway specified on bonded interface is installed according to "gateway x.x.x.x" (where x.x.x.x is a valid IPv4 address) specified in /etc/network/interfaces or files sourced per /etc/network/interfaces Actual Result: After reboot, route is not installed. Interface does work otherwise (I can ping the gateway on that subnet, for instance). 'ifdown -a' followed by 'ifup -a' (run with proper permission... so sudo) brings the gateway back until next reboot. Package: I'm not familiar enough to be certain what is causing this, but I was seeing this in beta2 of 16.04 as well. *username snipped*@*hostname snipped*:~$ lsb_release -rd Description: Ubuntu 16.04 LTS Release: 16.04 *username snipped*@*hostname snipped*:~$ apt-cache policy ifenslave ifenslave: Installed: 2.7ubuntu1 Candidate: 2.7ubuntu1 Version table: *** 2.7ubuntu1 100 100 /var/lib/dpkg/status *username snipped*@*hostname snipped*:~$ apt-cache policy ifupdown ifupdown: Installed: 0.8.10ubuntu1 Candidate: 0.8.10ubuntu1 Version table: *** 0.8.10ubuntu1 100 100 /var/lib/dpkg/status /etc/network/interfaces ---------------------------------- # This file describes the network interfaces available on your system # and how to activate them.
