cannot import name TracError

[djoseph@…]

Hi,

We upgraded Ubuntu from Breezy to Dapper (6.10) and now trac is broken. I can't find anything on how to fix this for the life of me. Here is what we get:

Oops…

Trac detected an internal error:

cannot import name TracError

Traceback (most recent call last):
  File "/usr/share/trac/cgi-bin/trac.cgi", line 19, in ?
    from trac.web import cgi_frontend
  File "/usr/lib/python2.4/site-packages/trac/web/__init__.py", line 1, in ?
    from trac.web.api import *

  File "/usr/lib/python2.4/site-packages/trac/util/__init__.py", line 30, in ?
    from trac.core import TracError
ImportError: cannot import name TracError

Any help is appreciated, thanks.

Forgot… we are using Python 2.4.3

This is an installation issue, please ask for support on the MailingList.

Try uninstalling Trac with the Ubuntu package manager, verify that all Trac files have been removed on your server, and install a fresh Trac copy with the package manager.

You seem to have code from a mix of Trac versions installed. This is probably the result of installing both the Trac Ubuntu package and another version from source over top of each other. Uninstall the "trac" package, remove the trac folders from /usr/lib/python2.4/site-packages and /usr/share and then reinstall Trac fresh. As eblot mentioned support and installation issues are typically handled on the MailingList, so please send further questions about this issue there.
