[ckan-discuss] Problem installing CKAN on debian lenny

Fri Mar 18 18:23:48 GMT 2011

Hey Everyone,

I am trying to open a open datastore, we want to use our own ckan
instance. We have our own server but we are having problems installing the
instance on it. The server is running Debian Lenny and Python 2.5.5. First
i tried the apt repository, but when I was about to initialize the
database, I got the following problem. After that I tried the developers
installation and there I god the same error while initializing the
database.

paster --plugin=ckan db init --config=development.ini
AttributeError: 'unicode' object has no attribute 'get_extension'

The complete traceback is:
Traceback (most recent call last):
