Description Erik Damrose

We received information that after updating to UCS 4.4-2 errata 348 an ImportError can occur, e.g.

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/univention/management/console/protocol/modserver.py", line 103, in _load_module
    self.__module = __import__(file_, [], [], modname)
  File "/usr/lib/pymodules/python2.7/univention/management/console/modules/uvmm/__init__.py", line 45, in <module>
    from univention.management.console.modules.uvmm.profiles import Profiles
  File "/usr/lib/pymodules/python2.7/univention/management/console/modules/uvmm/profiles.py", line 46, in <module>
    univention.admin.modules.update()
  File "/usr/lib/python2.7/dist-packages/univention/admin/modules.py", line 123, in update
    os.path.walk(dir, _walk, p)
  File "/usr/lib/python2.7/posixpath.py", line 239, in walk
    walk(name, func, arg)
  File "/usr/lib/python2.7/posixpath.py", line 231, in walk
    func(arg, top, names)
  File "/usr/lib/python2.7/dist-packages/univention/admin/modules.py", line 108, in _walk
    m = __import__(mod, globals(), locals(), name)
ImportError: No module named mailquota

See https://help.univention.com/t/13585

It seems some in some directories the __init__.py does not contain 
__path__ = __import__('pkgutil').extend_path(__path__, __name__)

[4.4-2 22f9b8e253] Bug #50493: Add missing extend_path in handler namespace packages

Package: univention-directory-manager-modules
Version: 14.0.14-17A~4.4.0.201911131922
Branch: ucs_4.4-0
Scope: errata4.4-2

hooks.d/__init__.py doesn't need this because it's imported via import_hooks() which goes the whole sys.path along.
