Error in console after fresh omv4 install

I am install omv4 on debian4 (netinstall) and now when i try apt-get update i see the next string:

Exception ignored in: <function WeakValueDictionary.__init__.<locals>.remove at 0x7f582f5b4730>
Traceback (most recent call last):
File "/usr/lib/python3.5/weakref.py", line 117, in remove
