dpkg: error processing package odn-simple (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
odn-simple
E: Sub-process /usr/bin/dpkg returned an error code (1)

Possible cause http://pypi.python.org/simple/ no longer accessible due to "force SSL".

Workaround:

• do install: apt-get install odn-simple
• cd /usr/share/python/odn-ckan-shared/
• . bin/activate
• pip install --index-url=https://pypi.python.org/simple/ requests==2.6.2
• repeat install: apt-get install odn-simple
