You do have several packages installed that aren't from the official
Ubuntu repositories

Obsolete: boot-repair boot-sav cordova-cli curlew dus freshplayerplugin
gloobus-preview google-chrome-stable google-earth-stable guidus intel-
linux-graphics-installer  mkusb oracle-java8-installer sublime-text
viber woeusb

Title:
  Upgrade from ubuntu-gnome 16.10 to 17.04 fails

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  Reverts back to 16.10 after reporting the failure could be caused by

  * Upgrading to a pre-release version of Ubuntu
  * Running the current pre-release version of Ubuntu
  * Unofficial software packages not provided by Ubuntu"

  The first two are not true.
