[Bug 1310194] [NEW] Upgrade from 13.10 to 14.04 failed

[Neeraj Nandakumar]

Public bug reported:

I ran the command 
   sudo do-release-upgrade -d 

That resulted in:
...

Checking package manager
Reading package lists... Done    
Building dependency tree          
Reading state information... Done
Building data structures... Done

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.
