Bug Description

I get the following error message:

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.

This seems to be due to some python packages which you've installed from a PPA.

libpython3.3 3.3.0-1irie1~precise1 1
libpython3.3-minimal 3.3.0-1irie1~precise1 1
libpython3.3-stdlib 3.3.0-1irie1~precise1 1
libpython3.4 3.4.0-2ubuntu1irie1~precise1 0
libpython3.4-minimal 3.4.0-2ubuntu1irie1~precise1 1
libpython3.4-stdlib 3.4.0-2ubuntu1irie1~precise1 1

You'll need to install the official package versions of any packages from that PPA for the upgrade to proceed successfully.

I could work around the problem by creating a 14.04 sources.list with the Ubuntu sources.list creator and executing sudo apt-get update && sudo apt-get dist-upgrade. Repeatingly executing sudo apt-get -f install && sudo apt-get dist-upgrade finally got me rid of any errors. So far the system seems to be running.
