Bug is not fixed in Raring.

Traceback (most recent call last):

    from aptdaemon.gtkwidgets import (AptErrorDialog,
ImportError: cannot import name AptMessageDialog

The AptMessageDialog was deprecated some time ago, since the concept of messages was removed from aptdaemon.

The widgets gets imported but is never used.

See the attached patch for a fix.

Thanks, i'll apply later on after I can validate. I'm also working on a python3, gobject introspection port for MCC, but it's got a lot of problems right now.

[Alexander Goodall (lagroth)]

I'd like to be able to try the patch. To do this would I have to compile Mythtv?

[Sebastian Heinlein (glatzor)]

Oh, the patch did not find its way into the raring release? That is a pitty.

You don't need to compile anything. Just open /usr/bin/mythbuntu-control-center in a text editor as root and remove the AptMessageDialog from the imports. You have to leave the closing bracket.

[Alexander Goodall (lagroth)]

Thank you, I'd just got this point. I'm happy to fiddle with txt files but compiling seems a bit beyond me at the moment. I can confirm that patch you submitted fixes the error for me. Appreciate you spending the time on this, Mythbuntu-control-centre makes my life so much easier.

Thanks for the fix, glatzor; it worked a treat.

Let's hope that this gets into the next release.

Still seeing this in Ubuntu 13.10 Saucy Salamander with mythbuntu-control-centre package version: 0.63-0ubuntu2

I can verify that the patch attached to this issue works and the mythbuntu-control-centre app opens after I've applied it!

Thanks @Sebastian ;-)

[Mario Limonciello (superm1)]

This has been fixed in 14.04 for the next release of Mythbuntu.

[mtbdrew (mtbdrew)]

installed mcc today after making sure my install of 13.10 was updated. Issue is still affecting Saucy.

[mtbdrew (mtbdrew)]

Easy fix run:

sudo gedit /usr/bin/mythbuntu-control-centre

Remove one line so you only have following:

from aptdaemon import client
from aptdaemon.enums import *
from aptdaemon.gtkwidgets import (AptErrorDialog,
                              AptProgressDialog)

UIDIR = '/usr/share/mythbuntu/ui'

Save and restart MCC
