Upgrading a CKAN 2 package install to a new patch release

Note

Before upgrading CKAN you should check the compatibility of any custom themes or extensions you’re using, check the changelog, and backup your database. See Upgrading CKAN.

Patch releases are distributed in the same package as the minor release they belong to, so for example CKAN 2.0, 2.0.1, 2.0.2, etc. will all be installed using the CKAN 2.0 package (python-ckan_2.0_amd64.deb):

1. Download the CKAN package:

   wget https://packaging.ckan.org/python-ckan_2.0_amd64.deb
   

   You can check the actual CKAN version from a package running the following command:

   dpkg --info python-ckan_2.0_amd64.deb
   

   Look for the Version field in the output:

   ...
   Package: python-ckan
   Version: 2.0.1-3
   ...
   

2. Install the package with the following command:

   sudo dpkg -i python-ckan_2.0_amd64.deb
   

   Your CKAN instance should be upgraded straight away.

   Note

   If you have changed the Apache, Nginx or who.ini configuration files, you will get a prompt like the following, asking whether to keep your local changes or replace the files. You generally would like to keep your local changes (option N, which is the default), but you can look at the differences between versions by selecting option D:

   Configuration file `/etc/apache2/sites-available/ckan_default'
    ==> File on system created by you or by a script.
    ==> File also in package provided by package maintainer.
      What would you like to do about it ?  Your options are:
       Y or I  : install the package maintainer's version
       N or O  : keep your currently-installed version
         D     : show the differences between the versions
         Z     : start a shell to examine the situation
    The default action is to keep your current version.
   *** ckan_default (Y/I/N/O/D/Z) [default=N] ?
   

   Your local CKAN configuration file in /etc/ckan/default will not be replaced.

   Note

   The install process will uninstall any existing CKAN extensions or other libraries located in the src directory of the CKAN virtualenv. To enable them again, the installation process will iterate all folders in the src directory, reinstall the requirements listed in pip-requirements.txt and requirements.txt files and run python setup.py develop for each. If you are using a custom extension which does not use this requirements file names or is located elsewhere, you will need to manually reenable it.

3. Finally, restart uWSGI and Nginx:

   sudo supervisorctl restart ckan-uwsgi:*
   sudo service nginx restart

4. You’re done!

You should now be able to visit your CKAN website in your web browser and see that it’s running the new version of CKAN.
