Trac No Longer Operational After Trying To Install A Plugin With Webadmin

[anonymous]

I am running trac on an Apache 2.2 based Joomla 1.5x site.

I attempted to install the TracTicketDelete-2.0-py2.5 plugin using the Web-admin interface. The installation failed, and since then any attempt to access the trac system results in the following error in the browser: Server error!

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script.

If you think this is a server error, please contact the webmaster. Error 500

The traceback that is generated is as follows:

I really don't have any idea how to resolve this, and I now have a completely non-functional Trac system. I have seen some closed tickets that have something similar, but I don't think that they resulted in a non-functional system, and in any case, none of the user suggested fixes have any effect. I need to get this resolved ASAP, as our project is on hold until I can get this resolved.

Attempts to run a standalone server using tracd results in a blank page in the browser, and the following errors in the shell used to start tracd:

Looks like the plugin you had was wrongly packaged… that setup.py file got extracted directly in the $TRAC_ENV/plugins folder and later got interpreted as a self-contained plugin in a .py file…

Btw, was that an .egg file or directly the source .zip you downloaded from TracHacks?

Uploading such a .zip file won't work, I'm afraid. See TracPlugins for information about how to build plugins (usually simply a matter of doing python setup.py bdist_egg).
