Running "kubuntu-devel-release-upgrade" on the konsole (German system) gives:

Problem is in /usr/lib/python3/dist-packages/DistUpgrade/

Possible fix is to change the runDistUpgrader function as follows:
    def runDistUpgrader(self):
        args = [self.script, "--frontend=DistUpgradeViewKDE"] + self.run_options
        # now run it with sudo
        if os.getuid() != 0:
            os.execv("/usr/bin/kdesudo", ["kdesudo"] + args)
            os.execv(self.script, args)
        # we shouldn't come to this point, but if we do, undo our
        # inhibit sleep

"kubuntu-devel-release-upgrade" just worked for me. However, I did have errors in the modemmanager and nfs-common. But it looks like this bug can be closed.

Can someone else verify it works?

Can confirm this is fixed.
Why if this bug is a duplicate (as indicated at the top) why is it in "Confirmed" and not closed status? Maybe launchbad works different than bugzilla which I'm more familiar with. Would be nice if someone with the right knowledge and editing power could update that.

tags: added: wily
tags: added: vivid

@ foss-4:

It had turned out that the actual work needed to be done on the of Vivid Vervet - thats why this bug-report is a ducplicate. Thanks for confirmation this fixed the issue.

Happy kubuntuing !
