INSTALLED_APPS not defined in cartoview? – Ubuntu

I am trying to install geoserver and this error comes in cartoview when i run paver setup_geoserver:

File "/home/developer/cartoview/cartoview/settings.py", line 24, in <module>
INSTALLED_APPS += CARTOVIEW_INSTALLED_APPS
NameError: name 'INSTALLED_APPS' is not defined

I don’t know why this error is coming. This error is with many more variables like TEMPLATES , STATICFILES_DIRS , MEDIAFILES_LOCATION , etc.

I am following this documentation: https://cartoview.readthedocs.io/en/latest/installation/ubuntu/
and currently at GeoServer Installation.

I have tried to manually define the variables but it is giving other errors like index out of range. can someone kindly help?
