MySQL behavior has changed here, so you have few options:

• Use older MySQL version prior this change
• Use Ubuntu packages which did revert this change (see https://bugs.launchpad.net/ubuntu/+source/dbconfig-common/+bug/1563274)
• Wait for fixing dbconfig-common, see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=824537

Update: You can workaround this bug as described in answer from William Ardila.
