Can't open Gajim

Question

When I try to open Gajim using terminal on gnome I get the following:

Traceback (most recent call last):
  File "gajim.py", line 106, in <module>
    import common.configpaths
  File "/usr/share/gajim/src/common/configpaths.py", line 27, in <module>
    import tempfile
  File "/usr/lib64/python2.6/tempfile.py", line 34, in <module>
    from random import Random as _Random
  File "/usr/lib64/python2.6/random.py", line 47, in <module>
    from os import urandom as _urandom
ImportError: cannot import name urandom

Any idea how to fix this?

My OS is Mandriva 2010.1, Python is v2.6 upgraded from v2.4

Can you include more details about your OS (distribution, version) and the version of python on your machine to help in solving the problem? — Bichoy, Apr 19 '13 at 15:42

You are probably importing the wrong os.py module. Try starting python2.6 and then

>>> import os
>>> print os.__file__

That should be /usr/lib64/python2.6/os.py or /usr/lib64/python2.6/os.pyc. If it is not remove (or rename) the file that you found. If it is try:

>>> os.urandom(3)

This should give you a string of 3 characters. If it does, then gajim is finding the wrong os.py module. If you get the same error as when running gajim then look in the /usr/lib64/python2.6/os.py at the end urandom should be defined if it does not exist ( using the line if not _exists("urandom":).

If it is not defined, as seems to be the case for python-2.6.5-2.5mdv2010.2.x86_64, and /dev/urandom exists you could try to re-add the code:

if not _exists("urandom"):
    def urandom(n):
        """urandom(n) -> str

        Return a string of n random bytes suitable for cryptographic use.

        """
        try:
            _urandomfd = open("/dev/urandom", O_RDONLY)
        except (OSError, IOError):
            raise NotImplementedError("/dev/urandom (or equivalent) not found")
        try:
            bs = b""
            while n - len(bs) >= 1:
                bs += read(_urandomfd, n - len(bs))
        finally:
            close(_urandomfd)
        return bs

I got: `/usr/lib64/python2.6/os.pyc` – Nx212 Apr 19 '13 at 16:11
I updated the things to test in the answer. – Anthon Apr 19 '13 at 16:20
`>>> os.urandom(3)` got me this: `>>> os.urandom(3) Traceback (most recent call last): File "", line 1, in AttributeError: 'module' object has no attribute 'urandom' >>> ` – Nx212 Apr 19 '13 at 16:33
can you look at the last 20 lines or so of /usr/lib64/python2.6/os.py? That should have the if statement in there. – Anthon Apr 19 '13 at 16:38
I'm afraid I can't find `if not _exists("urandom":)` in os.py – Nx212 Apr 19 '13 at 16:50
Which version of 2.6 did you install ( I have been looking at 2.6, self-compiled, running under Ubuntu 8.04 ). – Anthon Apr 19 '13 at 16:51
python-2.6.5-2.5mdv2010.2.x86_64 – Nx212 Apr 19 '13 at 16:58
That is definitely in the 2.6.5 source distribution, so mandriva took it out (also reported [here](https://answers.launchpad.net/hplip/+question/201039)). Looks like that mandriva version does not have `/dev/urandom` for some reason. – Anthon Apr 19 '13 at 17:08
But I found that `urandom` exists in the directory `/dev` – Nx212 Apr 19 '13 at 17:23
I get offers to move this discussion to chat, but unfortunately you have not enough reputation to be able write there. I added the lines from the source distribution, can you add those to your os.py? – Anthon Apr 19 '13 at 17:36
