package python-uniconvertor 1.1.2-1 failed to install/upgrade: subprocess post-installation script returned error exit status 1

Binary package hint: python-uniconvertor

Upgraded to 8.10 beta and the upgrade-manager generated an error about python-uniconvertor. I looked at the bugs on launchpad and saw one with the same symptoms. That reporter had installed a different version from somewhere other than the Ubuntu repos. I do not think I ever installed this package from somewhere else.

After some Googling I found similar errors. A proposed fix is to add overwrite-local = 1 to /etc/python/debian_config.

I added this to the config file and ran sudo apt-get upgrade. This time things appeared to work, but I had several warnings on screen. Here they are:

@James
Can you please check if there is any relevant information in /var/log/pycentral.log ; and if so attach that.

[James Crow (the-crowbar)]

Andreas,

  That log does not give any indication of what went wrong. It is attached just in case.

[Andreas Wenning (andreas-wenning)]

Yeah, that is really not a useful log for anything.

Can I have you attach all the logs from the upgrade. They are located in /var/log/dist-upgrade/

[James Crow (the-crowbar)]

apt-term.log copied to apt-term.log.user and permissions changed for upload.

[Andreas Wenning (andreas-wenning)]

This is what i could dig out of term.log:

[Andreas Wenning (andreas-wenning)]

Looks like a problem with python-central in the logging code.

I'm no expert, but "Fatal IO error 9 (Bad file descriptor) on X server :0.0." could suggest that it can't handle not having a real frontend (which happens when run by update-manager).

[Jean-Baptiste Lallement (jibel)]

James, had you a previous version of uniconvertor installed for python 2.5 ? I guess so because you're talking about an upgrade from hardy to intrepid but hardy doesn't ship uniconvertor.

Thanks in advance.

[James Crow (the-crowbar)]

@Jean-Baptiste

  I never specifically installed any version of python-uniconvertor. Could it have been installed along with KDE 4.1? I did have that on my Hardy system before the upgrade. I don't know enough about apt and its logging to see if it was pulled in to meet a dependency sometime in the past.

[Andreas Wenning (andreas-wenning)]

I've been looking through the log-files. Package python-uniconvertor was installed (to meet a recommends from inkscape) during your dist-upgrade from hardy to intrpid; at least according to dpkg/apt it was a new install of that package.

[Jean-Baptiste Lallement (jibel)]

kde4 doesn't seem to depend on uniconvertor but I'm not familiar with kde4.
However pycentral fails because there's already a version of uniconvertor installed in /usr/lib/python2.5/site-packages/uniconvertor/ or /usr/share/pyshared/uniconvertor/ .
If the package replacement doesn't appears in the log file then there is a chance it was installed manually otherwise it means there's a bug in pycentral.

[Andreas Wenning (andreas-wenning)]

@Jean-Baptiste
The important part is this:
Traceback (most recent call last):
   File "/usr/lib/python2.5/logging/__init__.py", line 753, in emit
     self.flush()
   File "/usr/lib/python2.5/logging/__init__.py", line 731, in flush
     self.stream.flush()
 IOError: [Errno 9] Bad file descriptor
 IOError: [Errno 9] Bad file descriptor
 IOError: [Errno 9] Bad file descriptor
 intrepid: Fatal IO error 9 (Bad file descriptor) on X server :0.0.

The log found higher up in this bug where it is complaining about duplicate files is becaouse it is the second run where the first pycentral run crashed (but it seems it generated the files okay in any case, that it now complains about in the second run)

[florinn (florinnaidin)]

I had the same problem when upgrading from Hardy to Intrepid
I removed python-uniconvertor (apt-get remove) and then installed it again (through Synaptic) and it worked

[pliz (pliz)]

uninstalling and installing helped me too

this very much sounds like a problem which should be fixed in jaunty/karmic. closing. please reopen if you see this again.
