The button was removed.

At least stuff like identity configuration. A user should be able to login and kontact should be immediately useable with default configs. So I guess about the same as the setup wizard?

do we need to create also the compelte configs in the user home?

This has been implemented but not yet tested

This task has nothing to do with syncing tag colors, because tag color is a property of a tag and not trasmitted via KEP:12 (folder annotations). That's why a removed the blocking tasks.

@machniak: okay thnaks for these informations, we will see if this is enough for a good UX.

Yes, this is caching. The cache is updated when you log in or visit Settings > Folders.

I now have a version, that successfully read/write the '/vendor/kolab/color' annotation. But if I look at roundcubemail, the colors are not updated.

Is in review process in upstream:
https://phabricator.kde.org/D448

It was decided earlier, that this would have low priority. But recently the discussion has come up in different forums, and the priority on this needs to be raised again.

Have installer install korgac in autostart.

Disabling KCrash with export KDE_DEBUG=1 helped.

Can either be fixed by trying to fetch repeatedly until the collections are available (they should become available eventually), or we can just ignore the issue since it only happens on first start and could be avoided by starting akonadi in advance with the system.

See akonadi/specialcollectionshelperjobs.cpp DefaultResourceJobPrivate::tryFetchResource(). There is no guarantee that the resource created its root collection yet, so we end up in a race condition.
