[Hardy] ImportError: No module named ext

[Simone Tolotti]

Binary package hint: python-xml

I don't know what's this related... I hope I've posted this bug in the right place...
I use a billing program written in python that worked flawlessy in Feisty and Gutsy, after upgrading to Hardy, it stopped working and give me this message:

simone@simone-desktop:~$ promoGest
Traceback (most recent call last):
  File "./promogest.py", line 25, in <module>

All dependencies seems satisfied.

Most of the functionality of python-xml was implemented in Python itself
starting with Python 2.4. For Hardy we've moved python-xml out of the
default path. I don't have the details handy, but your program will need
some small changes.

[Morten Kjeldgaard (mok0)]

This is a consequence of the fact the python-xml has been removed from hardy (see the discussion & explanation at bug #199014 ).

Python ships with its own implementation of the xml module, and that is where your program finds the xml.dom module. Unfortunately, the function "PrettyPrint" is not a part of that implementation, which is why you are getting an exception.

The package python-4suite-xml contains a PrettyPrint function, but you may need access to the source code of the billing program to make the necessary changes.

Alternatively, you can install the old python-xml package on your system.

Check the changelog of 0.8.4-10ubuntu1 at https://launchpad.net/ubuntu/+source/python-xml/ for a quick work around. A 'proper' fix for your application might be better. I'm not sure if the old XML modules will be removed..

python-xml was installed as a dependency of the app.
I'll ask application developers to fix this.
Thanks.
