我在 Ubuntu 中错过了我的 python3 版本20.04，调用后$ update-manager我收到以下错误，你能告诉我如何修复它吗
附言：我已经尝试了一些解决方案，但它们对我的情况不起作用。

答案1
已经过去很长时间了，但这是我的解决方案。
- 跑步
sudo systemctl status dbus。 - 您可以在此处看到一些错误。我们需要解决它们才能激活服务“com.ubuntu.SoftwareProperties”或任何其他服务。
例如：就我而言
- 没有 dbus_bindings。
解决方案：转到/usr/lib/python3/dist-packages/并创建到您的_dbus_bindings和 的链接_dbus_glib_bindings。
sudo ln -s _dbus_glib_bindings.cpython-***.so _dbus_glib_bindings.so等等。
- 没有 _gi 模块：按照此https://stackoverflow.com/a/60352723
最后你可以再次检查 dbus 状态，它应该是这样的：Successfully activated service '***'
就你的情况而言： 在此处输入图片描述
