ПРЕДОСТАВЛЕНИЕ САМБА

Я установил Samba на свой сервер Ubuntu, но на этапе PROVISIONING возникла такая проблема.

superuser@dww:~$ sudo samba-tool domain provision

  File "/usr/lib/python2.7/dist-packages/samba/ms_schema.py", line 261, in __parse_schema_file
    f = open(filename, "rU")

как это решить? Спасибо
