Pull all repositories. This is done by:

  pull.sh

There is only one environment for all sites. Make sure that you have it activated::

  . /usr/local/pythonenv/demo

And then you must run 

  make /home/luc/Makefile

(which runs initdb_demo in every demo site.)

And then 

  restart_services.sh

And finally click through all the demo sites on [url www.lino-framework.org/demos.html] in order to see whether they are still working.
