Facing errors in applying theming

[as...@vlabs.ac.in]

Hello Everyone, 

I am running with dogwood.3 installation of Open edX platform on ubuntu 14.04 machine. I am able to apply Stanford theme using the methods given in various documentations. 

If you visit https://github.com/edx/edx-platform/tree/master/themes, you get themes provided by edx platform.

Looks like edx.org and red-theme are provided as individual themes. 

I would like to use edx.org or red-theme to theme my edx instance. I am using the following steps -

1. mkdir /edx/app/edxapp/themes/default

2. Copy the contents of edx.org into /edx/app/edxapp/themes/default

3. Run compilation commands given - https://github.com/edx/configuration/wiki/edX-Managing-the-Full-Stack#compile-assets-manually

When I run command paver update_assets lms --settings=lms , I get the following error
