Could not calculate the upgrade when updating from 12.04 to 14.04

[wuyihao]

The Report:

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.

I've installed three or four softwares.And now I'm updating from 12.04 to 14.04 and received the error report.
Thanks a lot XD.

Status changed to 'Confirmed' because the bug affects multiple users.

This is reproducible from a fresh install of 12.04.3 in a VM - see bug 1274672 for specifics of how I reproduced it.

This Bug also occurs when upgrading from 13.10 > 14.04.
Running update-manager and choosing continue will apply most of the available updates.
Running update-manager and choosing partial update (It launches the distribution update GUI) it then errors out as described above.

I was able to launch Synaptic, and "Mark All Updates" to download and install the remaining packages, now when running update manager it see the dist as up to date.

Here is the commit log of packages\changes that had to be made via Synaptic because of the "Could not Calculate" issue:

I wouldn't hold your breath, just filed yet another. Now a month on. They don't care because it's not mobile. Time to abandon Ubuntu now that the trendy boys don't care about it any more.
