ImportError: No module named gtk

Thanks for your bug. What does "env | grep PY" write? And "python -c "import
sys; print sys.path"?

"env | grep PY" doesn't print anything.

$ python -c "import sys; print sys.path"

what about "ls /usr/lib/python2.4/site-packages/gtk-2.0", "ls
/usr/lib/python2.4/site-packages/gtk-2.0/gtk"?

could you run "strace -e open python -c "import gtk"" and copy that to a comment?

Created an attachment (id=4257)
strace -e open python -c "import gtk"

From the strace I see that the search path maybe wrong:

In my system I have:
# ls -l /usr/lib/python2.4/site-packages/gtk-2.0/pangocairo.so
-rw-r--r-- 1 root root 10896 2005-09-25 23:12
/usr/lib/python2.4/site-packages/gtk-2.0/pangocairo.so

Instead, in the strace it's looks for:
/usr/lib/python2.4/site-packages/gtk-2.0/gtk/pangocairo.so

it seems that the "import gtk" works as expect.

what does "python -c "import gtk; print gtk.gtk_version"? update-manager runs
with sudo, maybe you have something set for it? Does pygtk-demo run as expected?

$ python -c "import gtk; print gtk.gtk_version"
(2, 8, 4)

$ pygtk-demo
Traceback (most recent call last):
  File "/usr/bin/pygtk-demo", line 7, in ?
    execfile(os.path.join(pygtklibdir, "pygtk-demo.py"))
  File "/usr/lib/pygtk/2.0/pygtk-demo.py", line 18, in ?
    import gobject
ImportError: No module named gobject

I don't have anything special for update-manager.

Do you still have that issue?

Well, I did a clean breezy install and all works ok. Maybe a hoary -> breezy upgrade issue only.

Is this a duplicate of bug #30514?

This problem appears to be on dapper too.

Rejecting that bug, that seems to be a local issue fixed for the submitter (if that was an upgrade issue we would have received other bugs about that). #30514 is probably an another issue. Feel free to reopen if you get the issue again.
