trying to do do-release-upgrade on Odroid

[Dariusz]

Hi, I dont know if this is the right place to post this question. I'm a rather newbie in dealing with stuff like this.

I'm unable to upgrade to 16-04 on odroid c1 device. Whole process seems to break at calculating changes.

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.
