Error sync after update local app

[LxPvlv]

• OS: Archlinux
• About Anki: Version 2.1.0a10
• Qt 5.8.0 PyQt 5.7.1

After update descktop app fulfilled daily tasks. Pressed 'Sinchronize with AnkiWeb' and got following error.

An error occurred. It may have been caused by a harmless bug, 
or your deck may have a problem. 
To confirm it's not a problem with your deck, please run Tools > Check Database. 
If that doesn't fix the problem, please copy the following
into a bug report:
Caught exception:

Local base and AnkiWeb were sinchronized. But this message appear every time. Check Dtabase - OK.

This was fixed in dae/anki@4430785122d57eb1f3564b9bd06f4636bda77e63. It wasn't related to anki-sync-server. I'm not sure if the maintainer of the Arch Linux anki package intentionally updated to an alpha version, but it seems a little early. Might cause some headaches for @dae.

Welcome to ArchLinux ;-)

So far I can see the issue with the alpha version. They change to python3. Nice to have but this also affects the server directly, if run on the same side:

I did some research and it looks like qtwebkit was phased out because it's unmaintained and riddled with security issues: https://www.archlinux.org/todo/phasing-out-qtwebkit/ The current stable version of Anki has a dependency on it, but Anki 2.1 doesn't (it uses qt5-webengine instead). That explains the update to an alpha version.

I confirm that applying the fix from here manually in /usr/share/anki/anki/collection.py works. It is a quick fix for those who wanna use the version from the official repositories.

[agrueneberg]

The anki package has been removed from the official repositories. It is recommended to use the binary version from https://apps.ankiweb.net/ instead.

[Akendo]

seems like bad idea....
