Are you upgrading with aptitude?

I got the same issue upgrading because a trigger was activated while upgrading python2.6/python2.6-minimal; the python2.6 updates were moving shutil across packages.

python2.6 correctly depends on python2.6-minimal (= ${binary:Version}), yet python2.6 was unpacked before python2.6-minimal.

I wonder if this is an aptitude bug or some dep loop somewhere, but I couldn't find the latter.

[Loïc Minier (lool)]

Retrying the upgrade will fix the issue here.

Ok; looks like an aptitude bug to me; nobody else reported this

I updated my (some days old) maverick installation with "apt-get upgrade" and ran into the same issue. So it's not only aptitude related.

[Steffen Möller (moeller-debian)]

Same here, out of the blue with maverick, otherwise always kept up to date:

$ sudo apt-get -u dist-upgrade ....

Processing triggers for python-gmenu ...
Rebuilding /usr/share/applications/desktop.en_US.utf8.cache...
Traceback (most recent call last):
  File "/usr/sbin/update-python-modules", line 11, in <module>
    import sys,os,shutil
ImportError: No module named shutil

 subprocess installed post-installation script returned error exit status 1
....
Errors were encountered while processing:
 python-gmenu
E: Sub-process /usr/bin/dpkg returned an error code (1)

[Steffen Möller (moeller-debian)]

The funny thing is that until another "apt-get install python-minimal" is performed, one cannot even report the bug with "ubuntu-bug", since this also requires the shutil module :)

[Jean-Baptiste Lallement (jibel)]

Could you please attach the file /var/log/dpkg.log to this report ? This will allow us to see how package installation was processed by dpkg. This might be a coincidence but this occurs only when upgrading python2.6 together with python-gmenu.

[Ryan Oram (infinityos)]

I fixed this by manually running "apt-get install python2.6-minimal" before running "apt-get dist-upgrade" again.

[dazza5000 (darran-kelinske)]

sorry, but i did another upgrade before saving the logs

Firstly, this is not an aptitude bug. Aptitude relies on APT to
determine the order in which to install/configure dependencies.
Let us not engage in reassign-pong until a clear culprit is determined.

Unpacked packages are not configured. The order of unpacking in this
case is rather irrelevent. It is the order of configuration which is
important however, the error occurs before any configuration is
attempted.

The error is:

Correct me if I am wrong with what follows.

Given that, at this point:
  - python2.6, python-minimal are both unpacked, but deconfigred; and
  - module shutil has changed places during this particular upgrade;

it is not safe to run any python code until these packages are
reconfigured. It is common practice to not disable running of python
code during a normal python upgrade because the packages are
previously installed and thus "working". This particular upgrade
causes the python system to not work for some specific modules.

The updated set of python packages in this case should be disabling
the running of python code until they are reconfigured.

To diagnose specifically what is going on here it may be necessary to
examine the particular .deb files involved:

libpython2.6_2.6.5+20100616-1ubuntu2_i386.deb
libpython2.6_2.6.5+20100706-1ubuntu1_i386.deb
python2.6_2.6.5+20100616-1ubuntu2_i386.deb
python2.6_2.6.5+20100706-1ubuntu1_i386.deb
python_2.6.5-5ubuntu3_all.deb
python_2.6.5-5ubuntu4_all.deb
python-minimal_2.6.5-5ubuntu3_all.deb
python-minimal_2.6.5-5ubuntu4_all.deb

and also the python-gmenu packages from around the same time.

Is there a service for Ubuntu similar to snapshot.d.n which could
provide such old files?
