Before trying the commands above, you should remove any third-party or
PPA packages from your computer. Go to Software & Updates -> Other
Software to find what PPAs you have installed. Then use `sudo apt
install ppa-purge ; sudo ppa-purge ppa_name` (replacing 'ppa_name' with
the relevant PPA, typing in multiple PPAs separated by spaces if
necessary). Then perhaps run `sudo apt update ; sudo apt upgrade` to
ensure everything is fully up-to-date. You're also going to have to
manually remove any software you've installed from DEB packages that
aren't from the repositories. Use `sudo apt package_name` (replacing
'package_name' with the name of the package) to remove these manually
(yes, you'll have to remember which packages you've installed manually).
After you've done all this, first try upgrading using the Software
Update program (as you were trying originally). If that still doesn't
work, try the commands I suggested in comment 3.

Title:
Cannot upgrade ubuntu from 14.04 LTS to 15.10 neither to 16.04 LTS
Status in ubuntu-release-upgrader package in Ubuntu:
New
Bug description:
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. "
"That for the English version stands for:
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"
