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

* Unofficial software packages not provided by Ubuntu
If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-
I've installed three or four softwares.And now I'm updating from 12.04 to 14.04 and received the error report.
