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
User might have installed other Softwares, as per their need.
It would be great, to display details what Softwares are causing Ubuntu Release upgrade.
Can Ubuntu be able to remove or upgrade them at back-end and notify user accordingly ??
