trac won't upload attachment files

[metin@…]

We are using trac_0.11.1 in ubuntu 9.04 with python 2.6.2 and mod_python 3.3.1 — all of them installed via apt-get (stock ubuntu packages).

Trac fails to upload files.

1.I go to a ticket. and click "attach file"

2. The page for attaching files appears.
3. I click "browse" and attach the file.
4. I submit the attached file and another page appears (the normal page which lists the already attached files), but the uploaded file is not there. Only a button saying "attach" is there. If I press it, the whole cycle repeats again.

None of the logs has anything to say about it, apache can write to the required directories.

Dito: the trac version that is installed with Ubuntu 9.0.4 did not work for me either. The fix was:

• Remove ubuntu trac packages: sudo dpkg -r trac

An install from sources:

1. Dopwnload latest from: ​http://trac.edgewall.org/wiki/TracDownload/
2. cd /tmp
3. Extract
4. cd /tmp/Trac-<latest-version>
5. sudo python ./setup.py install
6. Add /usr/local/bin to PATH
7. /etc/init.d/apache2 restart

Note that I use SVN, users of BAZAR/GIT or MYSQL/POSTGRESS may need to add other packages
