Python3.1 compiling instead of 2.6

It looks like you had a partially installed libgcj-common package when you tried to install python-pyatspi.

What happens if you do this:
$ sudo dpkg --configure libgcj-common
?

Same thing, basically. I had actually 26 packages that were like this before. I removed them and started to reinstall only to notice the same thing happening:

> sudo dpkg --configure libgcj-common

dpkg: error processing libgcj-common (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 libgcj-common

It says "Compiling /usr/libpython3.1.."
then it raises en error, "raise Error, "nothing to do"". The error is because that's old Python syntax. In Python 3.1 it should be raise Error("nothing to do")...
It looks like apt should be using Python 2.6 (the system default) but is using 3.1 instead...

I'm not sure what libgcj-common has to do with Python, so I don't know why Python is involved when configuring it.

Also, why does it seem that there is Python 2 code in /usr/lib/python3.1?

These packages were just dependencies of other packages that installed..
It appeared that whatever I installed worked fine though I would end up with other packages showing up broken like this... I don't know if its that 2.5 and 2.6 would compile their own versions and then 3.1 would choke?? idk..
I can't verify any other operational difficulties other then this list of packages growing every time I install something.

What does "dpkg -S /usr/lib/python3.1/dist-packages/aotcompile.py /usr/lib/python3.1/dist-packages/classfile.py" give you?

hmmm:
>dpkg -S /usr/lib/python3.1/dist-packages/aotcompile.py /usr/lib/python3.1/dist-packages/classfile.py
dpkg: /usr/lib/python3.1/dist-packages/aotcompile.py not found.

OK, and "dpkg -S /usr/share/pyshared/aotcompile.py /usr/share/pyshared/classfile.py"?

I assume you're running Karmic? I don't currently have a Karmic box.

Sorry, I should have thought before to check here:

http://packages.ubuntu.com/search?searchon=contents&keywords=aotcompile.py&mode=exactfilename&suite=karmic&arch=any

I see that is part of libgcj-common.

If you uninstall that, are you then able to install python-pyatspi?

Yeah, I should have mentioned I'm 9.10.
>dpkg -S /usr/share/pyshared/aotcompile.py
libgcj-common: /usr/share/pyshared/aotcompile.py
> dpkg -S /usr/share/pyshared/classfile.py
libgcj-common: /usr/share/pyshared/classfile.py

So I guess that means that the package is installed for the 2.5 & 2.6 versions but 3.1 can't run them?
Is the ticket for Python support then?
It just seems like most things I install end up doing this with packages that are dependent.
I guess I could just get rid of python3.1. I'm not using it a this time, though I will be down the line (I'm doing web apps right now with Django and GAE which require Python 2).

I removed python-pyatspi, then removed libgcj-common. When installing python-pyatspi, ran into same problem:

This sounds to me like a problem with python-central installing links to python2 code in /usr/lib/python3.1, but I don't know enough about how it works to say for sure.

None the less, I appreciate you taking the time to check it out.
Python-central is an Ubuntu package?
Do you think I need to put it to a bug or just wait to see if someone else picks it up here?

OK, so it looks like the same problem affects both of those packages and probably every python2 package when you have python3 installed.

I had a very quick look to see if I could find an existing bug report for this, but I didn't see it. It's 1:22 am here, though and I didn't look very hard.

If I were you I'd have a better look to see if there's an existing bug report and if not, open one. (I might be wrong about python-central being to blame. I'm not very familiar with it, but it seems to me that your issues are caused by a bug.)

In the mean time, uninstall python3.1 if you can and I think that should work.

Didn't see your last message before posting my last one.

Yes, python-central is an Ubuntu package. As I said above, I might be wrong about it being to blame, though.

If you don't find an existing bug, open one and link this question to it. (At least I think that's how it's supposed to work here :)

Thanks Michael!

No problem :)
