[Bug 1309361] Re: Kubuntu upgrade from 13.04 to 13.10 failed: "could not calculate the upgrade"

In this case the problem was quite obvious, but it is very complex to
automatically identify the cause of an upgrade failure if even possible
at all. A technical user can go through the logs, try to understand what
is wrong and solve the problem himself.

Title:
  Kubuntu upgrade from 13.04 to 13.10 failed: "could not calculate the
  upgrade"

Status in “ubuntu-release-upgrader” package in Ubuntu:
  Invalid

Bug description:
  Description:    Ubuntu 13.04
  Release:        13.04

  I was upgrading from 13.04 to 13.10 using the GUI tool provided by KDE, the upgrade started well, but then suddenly reported "Could not calculate the upgrade"
  Unfortunately there is not much information provided by the updater. This is what I can see on the screen:
  --------------
  Upgrading Kubuntu to version 13.10
  Preparing to upgrade
  Setting new software channels -> failed
  Progress bar showing 99%
  "Fetching is complete"
  --------------
  I'm running Lenovo Thinkpad E530 with 64-bit system. There are some additional packages installed on my system, both from additionals PPA and "stand-alone", the most significant I can think of are Darktable and Lotus Notes.
  Upgrading my other laptop few days ago went well.

  This bug has been reported multiple times, but always closed as
  "invalid" or "expired". However it is still appearing.
