Sorry, I only just noticed it's not a removal but it being separated out into the new python-pyqtwebengine package.

In that case it would ofc be but a simple issue with anki's packaging, but it's still crashing for me with

See https://www.archlinux.org/todo/pyqtwebengine-split/

I'm told the move was done in testing, not staging, as it makes it easier to test which packages needed the change, and because the solution is to simply add a dependency (so affected users can simply pacman -S python-pyqtwebengine).

Either way, anki is now marked as completed, simply pacman -Syu and a new version of anki will be installed that adds the missing dependency.

Even with anki 2.1.8-2 resp. python-pyqtwebengine I now still get the (new) "'QWebEngineView' is not defined" startup crash.

"from PyQt5.Qt import *" no longer imports QtWebEngine modules, so they need to be explicitely imported now.

Yes, that fixes it. Thanks.

[Unrelated to this issue, in case demize reads this: There may be an issue with the upcoming Anki 2.1.9 that requires some users to act *before* updating, see "Changes in 2.1.9beta1" on https://apps.ankiweb.net/docs/beta.html ]
