[Bug 1385545] [NEW] 14.10 upgrade fails with the error : -" Could not calculate the upgrade"

[Chris Martin]

Public bug reported:

This error has occured on every system I have tried to upgrade to 14.10
I have removed all locally installed applications and applications installled from remote repositories.
I have also run autremove to get rid of orphaned packages

I am assuming that a library has been updated as part of another application install
and the version we have is ahead of the Ubuntu version, but I have no way of knowing which ones.

This happens on both 32 and 64 bit desktop versions.

I can't find any relevent logfiles that would indicate what went wrong
