Same problem. BTW, I do not have an Nvidia graphics card.

Hi Guys,

This looks similar, if not a duplicate of bug 303825 . bug 303825 seemed to be resolved by either reinstalling nvidia-common or removing the package completely. Care to comment if either resolve the issue reported here? For now I'm closing the "linux (Ubuntu)" task and keeping the "nvidia-common (Ubuntu)" task open. Thanks.

Same as michael37

I have exactly the same problem:

Setting up nvidia-common (0.2.4.1) ...
Traceback (most recent call last):
  File "/usr/bin/nvidia-detector", line 2, in <module>
    import NvidiaDetector
ImportError: No module named NvidiaDetector
dpkg: error processing nvidia-common (--configure):
 subprocess post-installation script returned error exit status 1

 nvidia-common

My system is up to date. Reinstalling the package did not change anything for me.

Workaround:

(cd /usr/bin/; sudo mv nvidia-detector nvidia-detector2)

Then finish installing nvidia-common

(cd /usr/bin/; sudo mv nvidia-detector2 nvidia-detector)

Should work. The problem looks like that it tries to execute the python script before the python libraries are installed!

I confirm that the workaround suggested by Andrew worked for me.

Confirming.

I did not understand the questions put to me by the Apport application. Is this (2.6.32-11-generic-pae) the upstream kernel? I have no idea. I was installing source and headers for that kernel because the Nvidia driver installer (the OEM's; I have no patience and insufficient wisdom to ken the distro's) asked for them.

I confirm that the workaround suggested by Andrew worked for me.
