[marco]

Public bug reported:

I cannot upgrade ubuntu from 14.04 LTS to 15.10 neither to 16.04 LTS.

Everytime I get the following error message:

Impossibile calcolare l'avanzamento

Si è verificato un problema irrisolvibile durante il calcolo 
dell'avanzamento. 

I motivi possono essere: 
* L'avanzamento a una versione di pre-rilascio di Ubuntu 
* L'esecuzione dell'attuale versione di pre-rilascio di Ubuntu 
* Pacchetti software non ufficiali non forniti da Ubuntu 

Se non vengono installati, segnalare il problema usando il comando 
«ubuntu-bug ubuntu-release-upgrader-core» in un terminale. 

right after it is evaluating the changes.
