Orca -无法保存配置

Question

我试图更改orca安装程序(orca -s)上的语音人，当我试图单击按钮'Apply‘或'OK’时，这个错误会出现在控制台中：

Gtk-Message: 12:48:35.589: GtkDialog mapped without a transient parent. This is discouraged.
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/orca/orca_gui_prefs.py", line 3054, in applyButtonClicked
    self.writeUserPreferences()
  File "/usr/lib/python3/dist-packages/orca/orca_gui_prefs.py", line 385, in writeUserPreferences
    keyBindingsDict)
  File "/usr/lib/python3/dist-packages/orca/settings_manager.py", line 485, in saveSettings
    self.profileKeybindings)
  File "/usr/lib/python3/dist-packages/orca/backends/gsettings_backend.py", line 232, in saveProfileSettings
    self._saveVoiceSettings(general['voices'], profile)
  File "/usr/lib/python3/dist-packages/orca/backends/gsettings_backend.py", line 615, in _saveVoiceSettings
    elif appSpecific == False and setEstablished == True:
UnboundLocalError: local variable 'setEstablished' referenced before assignment

我正在运行Ubuntu18.04.1 LTS桌面。

是否知道问题可能是什么，或者在哪里可以找到手动修改它的配置文件？？

谢谢你，朱利安

很明显，问题就在档案里：

/usr/lib/python3/dist-packages/orca/gsettings_backend.py

我设法绕过这个Ubuntu19.10移动文件到一个隐藏的文件！

sudo su
cd /usr/lib/python3/dist-packages/orca/
mv gsettings_backend.py .gsettings_backend.py
exit
reboot

系统回来后，我可以改变设置！
