Comment 28 for bug 24250

See info in #440229

workaround:

edit /usr/lib/python2.5/site-packages/UpdateManager/Core/utils.py

and add a line " return True" atthe beginning of the downloadable function:

##################################################"
def url_downloadable(uri, debug_func=None):
  """
  helper that checks if the given uri exists and is downloadable
  (supports optional debug_func function handler to support
   e.g. logging)

  Supports http (via HEAD) and ftp (via size request)
  """
  return True
  if debug_func:
    debug_func("url_downloadable: %s" % uri)
  import urlparse
....
##################################################"
