* error when running <tt>apt-get update</tt>: 

         error:  Traceback (most recent call last):
              File "/usr/lib/python3.5/weakref.py", line 117, in remove

* workaround
This seems to be fixable.

In short open <tt>/usr/lib/python3.5/weakref.py</tt> 

and change line 109 to:

    <tt>def remove(wr, selfref=ref(self), _atomic_removal=_remove_dead_weakref):</tt>

And line 117 to:

    <tt>_atomic_removal(d, wr.key)</tt>

Note you need to do this with spaces, not tabs as this will cause other errors.
