archweb, latest from git, master branch. (1dc867587da6b66ca575eb26f4f65cb9d67ffdb3)
I try to set it up, following all instructions in the README for `# Testing Installation`

It seems to work, until this step:

(archweb-env)22:09:00 dieter@ws archweb master ? ./manage.py loaddata main/fixtures/groups.json
Installing json fixture 'main/fixtures/groups' from absolute path.
Problem installing fixture 'main/fixtures/groups.json': Traceback (most recent call last):

If you're using virtualenv, it doesn't matter what python packages you installed, the virtualenv itself matters. `pip freeze`, even though that has no relevance here for future reference.

There is some oddness with the permissions and content type migrations due to a refactoring a while back, it appears. I took a quick look but there isn't a super quick fix- the particular permission and content type it is blowing up on is the news stuff, so if you just delete the two arrays in that json file dealing with news (add_news and change_news), you should be able to work around the problem for now.

I ran into the same error here, but removing the offending lines doesn't seem to fix it. Any other changes i need to make?

For now, try the following workaround:
./manage.py reset contenttypes (answer yes)
./manage.py loaddata contenttypes.json
   contenttypes.json (11.4 KiB)

That fixed the contenttypes error, but produces a new one for permissions:

Damn you Django. Remove the two arrays from the groups.json file containing the "add_signoff" permission for now, e.g.

- [
- "add_signoff",
- "main",
- "signoff"
- ],

I'm sorry to say it, but the error persists. ;-)
