I'm trying to upgrade my Kubuntu Wily 15.10 computer but it fails.
I'm doing this:
$ sudo do-release-upgrade -m desktop
This is what I get:
Calculating the 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.
I found this on

What can I do?
