没有名为“_dbus_bindings”的模块

我无法从 ubuntu 16.04 系统的 GUI 或终端打开“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/lib/python3/dist-packages/dbus/types.py", line 6, in <module>
    from _dbus_bindings import (
ModuleNotFoundError: No module named '_dbus_bindings'

我也无法使用 GUI 安装软件

我试过;

sudo apt-get install python-dbus

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

    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，而且我不想对系统造成任何损害。

答案1

我的情况是，从 3.6（ubuntu 18.04）升级到 3.7 时出现此错误消息：

$ pwd
/usr/lib/python3/dist-packages

$ sudo cp _dbus_bindings.cpython-36m-x86_64-linux-gnu.so _dbus_bindings.cpython-37m-x86_64-linux-gnu.so

$ sudo cp _dbus_glib_bindings.cpython-36m-x86_64-linux-gnu.so _dbus_glib_bindings.cpython-37m-x86_64-linux-gnu.so

答案2

另一个解决方案是创建符号链接。只需获取前面的第一个字符串.cpython并将其附加.so到它即可。

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

答案3

似乎软件包ssmtp未完全安装。您可以尝试使用 重新安装它，sudo apt install --reinstall ssmtp或者如果您的计算机上没有运行本地邮件服务，您可以使用 将其删除sudo apt remove ssmtp。
