[Bug 1543384] Re: dist-upgrade from 14.04 wants to install 16.04 which doesnt start any more

[Brian Murray]

It looks like DistUpgradeVeiwGtk3 was used and that should have used and
displayed the following announcement:

ReleaseNotes: http://archive.ubuntu.com/ubuntu/dists/xenial/main/dist-upgrader-all/current/DevelReleaseAnnouncement
ReleaseNotesHtml: http://archive.ubuntu.com/ubuntu/dists/xenial/main/dist-upgrader-all/current/DevelReleaseAnnouncement.html

Try using apt-get update and apt-get dist-upgrade when you boot into
console mode.

Title:
  dist-upgrade from 14.04 wants to install 16.04 which doesnt start any
  more

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

Bug description:
  I wanted to upgrade my Ubuntu 14.04 system to a new Version on Ubuntu.
  On the console I called
  apt-get update && apt-get dist-upgrade
  which successed.
  After that update-manager showed me that new target will be 16.04LTS which I appreciated most!
  However I was not informed that this is not yet finished at all.
  Without reading more in the internet, I clicked the upgrade and followed instructions.
  After a while the Screen got black and upgrade did not continue. 
  I used a console to save the distupgrad logs.
  After rebooting manually, the syste, does nto go into graphics mode and more as some package dependencies are broke (obviously).

  No idea how to fix this ;-(
