[ckan-dev] Upgrade from CKAN 2.5.2 to 2.5.9

Thu Sep 12 15:33:09 UTC 2019

Dear CKAN team,
I hope you can help me fix my upgrade of CKAN from 2.5.2 to 2.5.9.
We've been using 2.5.2 for a couple of years now. This month we've decided
to upgrade to 2.5.9.
That crashed our system.
Here are the steps I did, and up to the point where I got the error.
I'm not a python developer so please bear with me.

*Upgrading CKAN 2.5.2 to 2.5.9 on Rhel:*python --version
-> Python 2.7.5
pg_config --version
-> PostgreSQL 9.2.24

1. I created a backup of database.
2. Ran these:
. /usr/lib/ckan/default/bin/activate
cd /usr/lib/ckan/default/src/ckan

3. Ran these:
git fetch
git checkout ckan-2.5.9

4: Ran this:
pip install --upgrade -r requirements.txt

5. Ran this:
python setup.py develop

6. Restarted by Solr
/solr-4.10.4/bin/solr stop -p 8983
/solr-4.10.4/bin/solr start

Up to this point everything was installed well. No errors.

7*. This is where I get the error when running to upgrade my database:
paster db upgrade -c /etc/ckan/default/development.ini

Error below about: *"ImportError: No module named flask_app"*

Traceback (most recent call last):
