I had Ubuntu Studio 10.10 installed, and upgraded through each version
to 12.04.
When running Update Manager now, nothing appears. If I use the CLI, I
get the following error:
~$ update-manager
Traceback (most recent call last):
File "/usr/bin/update-manager", line 26, in <module>
from gi.repository import Gtk
File "/usr/lib/python2.7/dist-packages/gi/__init__.py", line 23, in <module>
from ._gi import _API, Repository
ImportError: /usr/lib/python2.7/dist-packages/gi/_gi.so: undefined symbol:
g_callable_info_skip_return
If I try to run other software, I get the same error, which includes: Ubuntu
Software Center, Ubuntu One and Apport/ubuntu-bug. All fail to show anything on
screen other than errors in the Terminal.
When trying to use ubuntu-bug to report this error I got a similar
error:

..
So I was unable to use ubuntu-bug to report the bug as that is also affected by
the same bug.
The bug seems to be this:
ImportError: /usr/lib/python2.7/dist-packages/gi/_gi.so: undefined
symbol: g_callable_info_skip_return
I have tried reinstalling Python 2.7 and some of affected packages, but
it makes no difference.
This error occured first when I had upgraded to 11.10 and then I had to use the
CLI to upgrade to 12.04. Before that in the earlier versions of Ubuntu, this
error did not occur.
I still have a copy of my 10.10 installation, and the file
/usr/lib/python2.7/dist-packages/gi/_gi.so did not exist in that, nor
did the gi folder.
