Issue 2

The end of an apt-get has the following message:

Exception ignored in: .remove at 0x7f7f749447b8>
 Traceback (most recent call last):
   File "/usr/lib/python3.5/weakref.py", line 117, in remove

Bug in Python

edit /usr/lib/python3.5/weakref.py and replace

def remove(wr, selfref=ref(self)):

with

def remove(wr, selfref=ref(self), _atomic_removal=_remove_dead_weakref):

and replace

_remove_dead_weakref(d, wr.key)

with

_atomic_removal(d, wr.key)
