Could you report the output of your systems call to this?: $ /usr/share/resolvconf/dump-debug-info
You can see that in my case resolvconf gets the uplink info via /run/resolvconf/interface/eth0.dhclient, how does your system get its config - dhcp as well? If so are you having a comparable file? Here mine from a more or less default zesty container. ###### Start of debugging information for resolvconf ###### ### ls -l /etc/resolvconf total 12 -rw-r--r-- 1 root root 511 Apr 1 2016
