The problem here was that you tried to run the command in the /usr/share/lyx/ 
directory where you do not have permissions to write (and that is the intent).

To reproduce what lyx is doing go instead to your user directory:

$ cd ~/.lyx
$ python /usr/share/lyx/

That will reproduce the same call as lyx does.

If you try to run that command in any other directory lyx will create all the 
files and directories present in the user directory. :-)

Tell us the result.
