Description

I'm using Ubuntu 18.10 on Lenovo Thinkpad: I get this error right after the install using Ubuntu software install ....after installed ...when pressing Launch button:

Error during startup: Traceback (most recent call last): File "/usr/share/anki/aqt/main.py", line 50, in init self.setupUI() File "/usr/share/anki/aqt/main.py", line 75, in setupUI self.setupMainWindow() File "/usr/share/anki/aqt/main.py", line 585, in setupMainWindow tweb = self.toolbarWeb = aqt.webview.AnkiWebView() File "/usr/share/anki/aqt/webview.py", line 114, in init self.focusProxy().installEventFilter(self) AttributeError: 'NoneType' object has no attribute 'installEventFilter'

Anki version: 2.1.0+dfsg-1 Updated: 11/17/2018 The error message won't reappear unless you uninstall and reboot O/S. Any help is appreciated. Thanks! DJ

Research direction
The error occurs in aqt/main.py and aqt/webview.py. The traceback shows that self.focusProxy() returns None in the AnkiWebView initialization. Investigate why focusProxy is None, likely due to Qt version mismatch or missing WebEngine setup. Check for related issues in the Anki repository.
