Can't Upgrade from 14.04.5-LTS to 16.04-LTS

Using the GUI Updater which has always showed "Upgrade available" but I have ignored it -- up until today. :) Then got the errors.


The only two packages that I am aware of are BackInTime (BiT) and Wine and both have their PPAs defined and checked. After the first go around of errors I disabled the PPAs for Wine and BiT and the ERROR1 message went away, but still got ERROR 2.


I tried this but same again...
Can't upgrade from 12.04LTS to 14.04LTS


How do I do the Upgrade?
OR, is there some way to push all my 14.04 programs and data over to a clean install of 16.04?



ERROR 1: Preparing to Upgrade


Third party sources disabled
Some third party entries in your sources.list were disabled. You can re-enable them after the upgrade with the 'software-properties' tool or your package manager.


ERROR2: Setting new software channels


Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade.
This can 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


If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.
