Internal Server Error(code 500) returned by apache

[oguya]

Deploying ckan with vanilla configs on Ubuntu 12.04 installs & configures all the components successfully.
But when you access the default ckan URL - http://hostname/ you get a HTTP code 500 error from Apache.

Not sure if you've solved this, but I came up on the exact problem while writing a similar playbook for deploying ckan.

For me, the solution was (so far) changing the following lines in my .conf file

<Directory {{ ckan_settings_path }}>
        Order allow,deny
        Allow from all
        Require all granted
</Directory>

to

<Directory {{ ckan_settings_path }}>
        Order allow,deny
        Allow from all
        Require all granted
        Satisfy Any
</Directory>

The addition of Satisfy Any seems to be the key.

Basically the config file 000-ckan-default.conf.j2 works on Apache 2.4 & above.

@scuerda
By default, Apache 2.2 uses Satisfy All[1] which ensures all specified criteria must be satisfied before a user is allowed in. On the hand using Satisfy Any works but it's less secure.

This is issue occurs on only Apache 2.2 & below which is available on Ubuntu 12.04. I don't see why I should create a fix for this, yet Ubuntu 12.04 is almost approaching its EOL & most people use Ubuntu 14.04 anyways ¯_(ツ)_/¯

Works for me!
