[ckan-dev] UBUNTU package installation

[Hildegard Gerlach]

Hello,

I had installed CKAN on UBUNTU as package installation and it had 
worked. Now I get errors but don't understand why. Some other software 
had been installed in the meantime and I am not sure if this can have 
changed something.
apache2 is used as WebServer

the configuration file for CKAN in sites-enabled is


WSGISocketPrefix /var/run/wsgi
<VirtualHost *:84>

     ServerName d01ri0702475.jrc.it
     #ServerAlias www.default.ckanhosted.com
     ServerAlias d01ri0702475.jrc.it
     WSGIScriptAlias / /etc/ckan/default/apache.wsgi

     # pass authorization info on (needed for rest api)
     WSGIPassAuthorization On

     # Deploy as a daemon (avoids conflicts between CKAN instances)
     #WSGIDaemonProcess ckan_default display-name=ckan_default

     #WSGIDaemonProcess d01ri0702475.jrc.it display-name=ckan_default

     #WSGIProcessGroup d01ri0702475.jrc.it

The error message is

I don't understand what I have to change. Do I need these 
WSGIDaemonProcess lines, and if yes, how ?

Thanks
