no module named '_dbus_bindings'

sudo ln -s /usr/lib/python3/dist-packages/_dbus_bindings.cpython-36m-x86_64-linux-gnu.so /usr/lib/python3/dist-packages/_dbus_bindings.so

其他module同样处理

language support cannot open

原因：将默认的python3由python3.6替换成了python3.7，报错在/var/log/syslog中，/usr/lib/python3/dist-packages/aptdaemon/client.py中使用了async作为变量名，在3.7中成为了关键字导致语法错误
几种解决办法：

• 将python3.7换回python3.6;
• 替换变量名;
