Upgrading a CKAN install from Python 2 to Python 3¶
These instructions describe how to upgrade a source install of CKAN 2.9 from Python 2 to Python 3, which is necessary because Python 2 is end of life, as of January 1st, 2020.
Backup your CKAN source, virtualenv and databases, just in case.
Upgrade to CKAN 2.9, if you’ve not done already.
You’ll probably need to deactivate your existing virtual environment:
The existing setup has the virtual environment here: /usr/lib/ckan/default and the CKAN source code underneath in /usr/lib/ckan/default/src. We’ll move that aside in case we need to roll-back:
sudo mv /usr/lib/ckan/default /usr/lib/ckan/py2
From this doc: Installing CKAN from source you need to do these sections:
