I've noticed that do-release-update made an half disaster: system now thinks that update is completed (it thinks it moved to 16.10) and software sources are modified to the new version. Apt upgrade tried to update all packages missing but it leaved system in a totally unusable and instable state. So I suggest to absolutely don't try to update packets after a failed try with do-release-upgrade...
