This crash has the same stack trace characteristics as bug #177567. 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.

The "usb" Python module comes from the python-usb package and this package is required by hal-cups-utils in Intrepid.

So for me it looks like that something in your system is broken.

Reopening since we got two new duplicates, this seems to affect Jaunty.

[Till Kamppeter (till-kamppeter)]

Please update the python-usb package to the newest version, it had to be adapted to Python 2.6.

[Till Kamppeter (till-kamppeter)]

Can you run

sudo /var/lib/dpkg/info/python-cups
sudo /var/lib/dpkg/info/python-cupshelpers
sudo /var/lib/dpkg/info/python-usb

and see whether this solves the problem? In this case this bug would be the same as bug 335543.

[Till Kamppeter (till-kamppeter)]

Correction, can you run

sudo /var/lib/dpkg/info/python-cups.postinst
sudo /var/lib/dpkg/info/python-cupshelpers.postinst
sudo /var/lib/dpkg/info/python-usb.postinst

and see whether this solves the problem? In this case this bug would be the same as bug 335543.

[Till Kamppeter (till-kamppeter)]

Looks like a problem in with the transition to Python 2.6 in python-central, according to IRC discussion with mvo and DktrKranz.

[Matthias Klose (doko)]

why should it be a python-central error, if the usb module cannot be imported, which is managed by python-support?

[Till Kamppeter (till-kamppeter)]

It seems that for the transition to Python 2.6 the post-install script of all Python libraries needs to be re-run (see also bug 335543). I do not know which package would be responsible for doing this on an update from Intrepid to Jaunty. I move it to python-support now. Perhaps it can be also the python package itself.

Based on http://www.ubuntu.com/getubuntu/releasenotes/904#python%20ImportError%20with%20systems%20upgraded%20before%20Ubuntu%209.04%20release%20candidate this should be fixed. Please reopen if not. Thanks.
