没有名为“_dbus_bindings”的模块

Question

我无法从GUI或我的ubuntu16.04系统的终端打开“软件和更新”

sudo software-properties-gtk
sudo: unable to resolve host dna-ws: Connection timed out
[sudo] password for localadmin: 
Traceback (most recent call last):
  File "/usr/bin/software-properties-gtk", line 37, in <module>
    from softwareproperties.gtk.SoftwarePropertiesGtk import SoftwarePropertiesGtk
  File "/usr/lib/python3/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 29, in <module>
    import dbus
  File "/usr/lib/python3/dist-packages/dbus/__init__.py", line 82, in <module>
    import dbus.types as types
  File "/usr/lib/python3/dist-packages/dbus/types.py", line 6, in <module>
    from _dbus_bindings import (
ModuleNotFoundError: No module named '_dbus_bindings'

我也不能使用GUI安装软件

我试过了

sudo apt-get install python-dbus

    sudo: unable to resolve host dna-ws: Connection timed out

    dpkg: error processing package ssmtp (--configure):

    E: Sub-process /usr/bin/dpkg returned an error code (1)

我不知道该怎么做才能解决这个问题，我不想对系统造成任何损害。

Answer 1

似乎包ssmtp还没有完全安装。您可以尝试用sudo apt install --reinstall ssmtp重新安装它，或者如果您不在计算机上运行本地邮件服务，则可以使用sudo apt remove ssmtp删除它。

Answer 2

另一个解决方案是创建一个符号链接。只需将第一个字符串放在.cpython之前，并将.so附加到其中。

sudo ln -s _dbus_bindings.cpython-36m-x86_64-linux-gnu.so _dbus_bindings.so
sudo ln -s _dbus_glib_bindings.cpython-36m-x86_64-linux-gnu.so _dbus_glib_bindings.so
