def close(self):
"""Send the quit message and close the socket"""
if self._closed:
raise err.Error("Already closed")
self._closed = True
if self._sock is None:
return
send_data = struct.pack('<iB', 1, COMMAND.COM_QUIT)
try:
self._write_bytes(send_data)
except Exception:
pass
finally:
sock = self._sock
self._sock = None
self._rfile = None
sock.close()
`sock.close()` complains about `sock` being None, `sock = self._sock`, so
`self._sock` must have been None, and `self._sock` was checked in `if
self._sock is None:` so `self._sock` must not have been None at that time. So
this status muct have been changed either in another thread (unlikely) or in
`self._write_bytes`.

No. You have to persuade debian package maintainers to update it. No other
version is install-able under our current policy.
