ImportError: No module named qt

[Andreas Blochberger]

Binary package hint: kdebluetooth

After a sudo apt-get dist-upgrade to Jaunty Alpha 5 this error popped up. Maybe this is a similar problem as in Bug #135893

This has something to do with Python 2.6, i've reported two other bugs with the same cause:

This error makes KDE 4.2 unusable. Plasma hangs as soon as i start any application. I don't know if this is related to this, though

[Apport retracing service (apport)]

This crash has the same stack trace characteristics as bug #135893. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.

[Jonathan Thomas (echidnaman)]

This should be fixed with the latest updates. KDE made some rather... invasive changes to the python bindings this time around.

[Andreas Blochberger (andreas-blochberger)]

As this bug returned, it seems not to be fixed. Bug #340088 proves that this problem still is here

[Jonathan Thomas (echidnaman)]

Are you sure you're up to date? It works for me.

[Ilja Pavkovic (ipavkovic)]

Works for me too, no bug anymore

[Andreas Blochberger (andreas-blochberger)]

I am sure i'm up to date. I do software updates twice a day, and this last crash just happened yesterday. Currently KDE doesn't work at all, so i'm trying it out after every update. Usually i only see that it does not work (i can't start any application in KDE and i see a lot of zombies in my process list), but yesterday apport reported this crash, when i returned in gnome.

What information do you need, to track this issue?

Same output from update-notifier-kde

michael@clu:~$ update-notifier-kde
Traceback (most recent call last):
  File "/usr/bin/update-notifier-kde", line 34, in <module>
    import dbus.mainloop.qt
ImportError: No module named qt

[Andreas Blochberger (andreas-blochberger)]

This probably is the same cause as in Bug #341568, so i'm going to mark it as duplicate of this. The re-installation of python-qt4-dbus made the error message go away, but it looks like the symptoms are still there.

[SRElysian (srelysian)]

strangely enough, i didnt notice my bluetooth icon was missing until I reinstalled dbus. I was originally trying to fix the update notifier problem, and on reboot... my bluetooth icon showed up. Hah, I still haven't seen the update notifier icon come up with anything new though.. usually (on 8.10) if i did a manual update it'd show up, but nothing now.

[mrvanes (mrvanes)]

update-notifier-kde was bumped to 0.15 yesterday and it now shows available updates correctly.
The last wrinkle now is that clicking on the notifier icon doesn't launch the update manager.

[Giordano Battilana (jordan83)]

I've upgraded to Kubuntu 9.04 beta about a week ago and notifications about software upgrades were not working. The Kdebluetooth icon also disappeared.
I investigated and found out that the command "update-notifier-kde" was failing with

$ update-notifier-kde
Traceback (most recent call last):
  File "/usr/bin/update-notifier-kde", line 34, in <module>
    import dbus.mainloop.qt
ImportError: No module named qt

I then found this bug page and (apparently) solved the issue by reinstalling the package python-qt4-dbus as suggested by Andreas.

Perhaps you should force the re-installation of such package because other users may be experiencing the same problem.

Cheers

This issue happened in Kubuntu Karmic Alpha 6.

[Paulino Ascenção (paulino.a)]

This is hapenning again in Kubuntu 9.04. When I try to upgrade to 9.10 with update-notifier.

paulino@kubuntup:~$ update-notifier-kde -d
Traceback (most recent call last):
  File "/usr/bin/update-notifier-kde", line 34, in <module>
    import dbus.mainloop.qt
ImportError: No module named qt

And solved after reinstalling package python-qt4-dbus
