AttributeError on client machine

Published: July 29, 2016 - 6:52 PM

Good morning,

The WAPT systems present locally on the workstations are starting to make mistakes.
When I try to "Upgrade the system" the page displays in white with a "Server Error" message.

The error in the task list is as follows:

Code: Select all

AttributeError: type object 'exceptions.Exception' has no attribute 'create'
I tried looking at the server side (Debian) but everything is working. I can access the repository from the workstations, I can ping it.

I tried using the command prompt by running "wapt-get update" then "wapt-get upgrade" and it displays this error:

Code: Select all

Exception at 005755E5: EIdHTTPProtocolException:
HTTP/1.1 500 Server Error.
The issue is occurring on several machines (70/1500), the problem is starting to become critical as I can no longer perform any updates.

Thank you,

I'm adding the logs in the hope that someone can figure out where the problem is coming from.
Almost my entire fleet can no longer receive updates.
I attempted a complete reinstallation of WAPT on the client machine manually but I still get the same error message.

I tried restarting the server, but it didn't change anything.
The logs located in /var/log don't give me any more information.

I tried looking on the git repository and the only link I found is https://github.com/tranquilit/WAPT/blob ... _init__.py.
Unfortunately, I am unable to read this code.

Line 465:

Code: Select all

	def __getattr__(self, attr):
		args=self._prop_map_get_.get(attr)
		if args is None:
			raise AttributeError("'%s' object has no attribute '%s'" % (repr(self), attr))
		return self._ApplyTypes_(*args)

	def __setattr__(self, attr, value):
		if attr in self.__dict__: self.__dict__[attr] = value; return
		try:
			args, defArgs=self._prop_map_put_[attr]
		except KeyError:
			raise AttributeError("'%s' object has no attribute '%s'" % (repr(self), attr))
		self._oleobj_.Invoke(*(args + (value,) + defArgs))
	def _get_good_single_object_(self, obj, obUserName=None, resultCLSID=None):

	def _get_good_object_(self, obj, obUserName=None, resultCLSID=None):
return _get_good_object_(obj, obUserName, resultCLSID)

For your information, I just solved the problem.
A group had its own group as a dependency. I simply removed it, and WAPT is working again.
The error explained that there was an infinite loop in the dependencies.
