I am a newbie to N900 and Maemo 5 platform.

I am trying to use PyMaemo on Scratchbox. I installed python2.5 and was successfully able to run 'Hello World" on the scratchbox. now I am trying to use PyQt4 to create a GUI based application.

I get the following error:
[sbox-FREMANTLE_X86: ~/MyApps] > python2.5 texteditor.py
Traceback (most recent call last):
File "texteditor.py", line 2, in <module>
from PyQt4 import QtGui
ImportError: No module named PyQt4
[sbox-FREMANTLE_X86: ~/MyApps] >

Now, from the different mail threads I gathered that I need to install the python2.5-qt4 package. I accordingly modified the /etc/apt/sources.list file and added the following
deb http://repository.maemo.org/extras-devel fremantle free non-free
deb http://repository.maemo.org/extras-testing fremantle free non-free

I then used
[sbox-FREMANTLE_X86: ~/MyApps] > apt-get update

[sbox-FREMANTLE_X86: ~/MyApps] > apt-get install python2.5-qt4
Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package python2.5-qt4
[sbox-FREMANTLE_X86: ~/MyApps] >

Could anyone please help me with this problem.

Thanks

try:

deb http://repository.maemo.org/extras-devel/ fremantle free non-free
deb http://repository.maemo.org/extras-testing/ fremantle free non-free

and possibly:
