OMV 4.x apt install报错

problem

在装完OMV (ver. 4.1.22) 之后，打算用apt装一些软件，然后就遇到如下报错:

Exception ignored in: <function WeakValueDictionary.__init__.<locals>.remove at 0x7f81db3bc730>
Traceback (most recent call last):
  File "/usr/lib/python3.5/weakref.py", line 117, in remove
TypeError: 'NoneType' object is not callable
Exception ignored in: <function WeakValueDictionary.__init__.<locals>.remove at 0x7f81db3bc730>
Traceback (most recent call last):
  File "/usr/lib/python3.5/weakref.py", line 117, in remove
TypeError: 'NoneType' object is not callable

solution

Google搜了一波之后，在 github 上找到了解决方案：

首先打开/usr/lib/python3.5/weakref.py 这个文件：

vim /usr/lib/python3.5/weakref.py

然后把第109行改成

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

第117行改成

_atomic_removal(d, wr.key)

wq保存一下，再试试apt，问题搞定。
