SRU template applied. ** Changed in: anki (Ubuntu Eoan) Status: Confirmed => Fix Committed
** Description changed: + [Impact] + + Due to changes in PyQt (according to Arch), the Anki application fails + to run because library imports have been altered in a way that causes + the application to not execute and start under any circumstances. + + This makes the application as is currently unusable. + + + [Test Case] + + (1) Install Ubuntu Disco or Ubuntu Eoan. + + (2) Install anki from repositories as-is (2.1.8+dfsg-1) + + (3) Attempt to run `anki` on command line, you get the traceback stated + in the original description. + + (4) Use the PPA or the version in the repos/proposed. + + (5) Anki properly runs without error and starts up as expected. + + + [Regression Potential] + + From a code perspective, the only thing we do is we pull in all the + libraries and classes from PyQt5.QtWebEngineWidgets. In the long term + this could cause breakages if PyQt changes again. + + However, in the intervening *short term*, this change does not introduce + any major code or functional changes other than to make the various + classes available for use, and the regression risk from this change is + minimal. + + + [Additional Information] + + This was tested in a Disco and an Eoan VM running inside VMware. The + test cases were both able to be tested without issue there, and are as + written. + + There is a PPA with these changes available, linked in the comments. + + + [Original Description] + Trying to start Anki version 2.1.8+dfsg-1 from Ubuntu 19.04 fails with the following error: Traceback (most recent call last): - File "/usr/bin/anki", line 6, in <module> - import aqt - File "/usr/share/anki/aqt/__init__.py", line 32, in <module> - import aqt.forms - File "/usr/share/anki/aqt/forms/__init__.py", line 44, in <module> - from . import about - File "/usr/share/anki/aqt/forms/about.py", line 42, in <module> - from aqt.webview import AnkiWebView - File "/usr/share/anki/aqt/webview.py", line 90, in <module> - class AnkiWebView(QWebEngineView): + File "/usr/bin/anki", line 6, in <module> + import aqt + File "/usr/share/anki/aqt/__init__.py", line 32, in <module> + import aqt.forms + File "/usr/share/anki/aqt/forms/__init__.py", line 44, in <module> + from . import about + File "/usr/share/anki/aqt/forms/about.py", line 42, in <module> + from aqt.webview import AnkiWebView + File "/usr/share/anki/aqt/webview.py", line 90, in <module> + class AnkiWebView(QWebEngineView): NameError: name 'QWebEngineView' is not defined This appears to be due to changes in the PyQt, as described in this Arch bug report: https://bugs.archlinux.org/task/61710 The patch suggested there by Antonio Rojas works on my Ubuntu 19.04 system, too: --- /usr/share/anki/aqt/qt.py.orig 2019-02-10 22:41:21.648827256 +0100 +++ /usr/share/anki/aqt/qt.py 2019-02-10 22:38:17.798020886 +0100 @@ -13,7 +13,7 @@ from PyQt5.Qt import * # trigger explicit message in case of missing libraries # instead of silently failing to import -from PyQt5.QtWebEngineWidgets import QWebEnginePage +from PyQt5.QtWebEngineWidgets import * try: from PyQt5 import sip except ImportError: ** Changed in: anki (Ubuntu Disco) Assignee: Thomas Ward (teward) => (unassigned) ** Changed in: anki (Ubuntu Disco) Status: Confirmed => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1825722 Title: Anki fails to start because QWebEngineView is not defined (missing import) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/anki/+bug/1825722/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
