Upgrade from trac 0.10.3 to 0.12 mod_python database error

Question

Hello!

I´m trying to upgrade trac! from 0.10.3 to 0.12. Need help, i basiclally did steps shown here

http://trac.edgewall.org/wiki/TracUpgrade

So i went through this commands without errors:

todasana:~# easy_install —upgrade Trac0.12 Searching for Trac0.12

---

todasana:~# trac-admin /usr/local/apache2/htdocs/trac_catw3 upgrade

---

todasana:~# trac-admin /usr/local/apache2/htdocs/trac_catw3 wiki upgrade

---

todasana:~# trac-admin /usr/local/apache2/htdocs/trac_catw3 repository resync ‘*’

---

Didn´t do Step 5 Refresh static resources, because i did not understand it, and i think it does not apply to me: trac-admin /path/to/env deploy /deploy/path

then i restarted apache: /etc/init.d/apache2 restart

got this error in the browser now:

TracError: Database newer than Trac version

*got Python 2.4.4 (#2, Jan 24 2010, 11:19:18)
mysql: Server version: 5.0.32-Debian_7etch11-log Debian etch distribution*

IT OCCOURS TO ME THAT SOMETHING SHOULD BE DONE WITH THE DATABASE OR CONFIG FILES, BUT NOT SURE WHAT BECAUSE THERE IS NOTHING IN THE DOCS ABOUT IT!
Guys have a great day!!

Yesterday i fixed the error, how ever got a new one! And the way i fixed the previous one i did not like, i think it was not really fixed and i'm getting more errors because of it

I changed a value on the database: UPDATE system SET value = ‘19’. (orginal value was 26)

Source control, and navigation work fine, however can´t create new ticket! i get:

Oops… Trac detected an internal error:

If you think this really should work and you can reproduce it, you should consider reporting this problem to the Trac team.

Go to http://trac.edgewall.org/ and create a new ticket where you describe the problem, how to reproduce it. Don't forget to include the Python traceback found below.

TracGuide — The Trac User and Administration Guide Python Traceback

Traceback (most recent call last): File "/var/lib/python-support/python2.4/trac/web/main.py", line 387, in dispatch_request dispatcher.dispatch(req) File "/var/lib/python-support/python2.4/trac/web/main.py", line 237, in dispatch resp = chosen_handler.process_request(req) File "/var/lib/python-support/python2.4/trac/ticket/web_ui.py", line 302, in process_request get_reporter_id(req, 'author')) File "/var/lib/python-support/python2.4/trac/ticket/web_ui.py", line 658, in _insert_ticket_data actions = TicketSystem(self.env).get_available_actions(ticket, req.perm) File "/var/lib/python-support/python2.4/trac/ticket/api.py", line 83, in get_available_actions return [action for action in actions.get(ticket['status'], ['leave']) File "/var/lib/python-support/python2.4/trac/ticket/model.py", line 104, in getitem return self.values[name] KeyError: 'status'

HOW EVER, if i change the database system value to 20, i THE SITE WORKS, however when i create a ticket i get the original error:

any ideas ?

Answer 2

It sounds like the version of Trac being run by Apache is the older version and not the version you just installed. Verify that the version of Trac you are running is the version you think you are running.
