You're using Python 2.3, which is not supported anymore starting with Trac 0.12.

And with Trac 0.13dev, you'll even need Python 2.5.

See TracInstall and 0.13/TracInstall.

You mean there's no testing to check for the required version?

That seems silly to me.

Replying to hm2k:

You have a point there. We should probably add a check to setup.py.

[hm2k]

Yes, a check would be useful. I'd hope this has been implemented by now.

With regards to this, I decided the only thing to do was to upgrade the system from CentOS 4 to CentOS 5, only to find that Python is only 2.4:

[root@vps112 ~]# rpm -q python
python-2.4.3-27.el5_5.3

The reason for this is probably due to backporting: ​http://tinyurl.com/r77l2

It's official: I'm unable to setup/install Trac on CentOS. Am I overlooking something here?

Can anyone advise further?

[rblank]

Install 0.12.1 or from the 0.12-stable branch, which support Python 2.4.

I'll add the version check.

Version check added in [10364].
