APT 返回 TypeError 的错误

最近在为公司整理工作环境，部署 OMV 4 时，发现 apt update 指令会引发如下错误：

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

找了一下，根据 OVM 的论坛回复，应该是 python 的 bug，同时提供了 fix 。

具体方法就是修改 /usr/lib/python3.5/weakref.py 文件的 109 行和 117 行：

@@ -106,15 +106,15 @@ def __init__(*args, **kw):
         self, *args = args

                     self._pending_removals.append(wr.key)
                 else:

                     # can be called asynchronously by the GC

         self._remove = remove
         # A list of keys to be removed
         self._pending_removals = []

Happy Coding
