I have tried some stuff to get the preview of odt and other Document-Files to work (as it does for example in konqueror), but didn't manage to get it working. Pdf preview is working smoothly but not the odf-formats. This would be a great feature of dolphin for people doing a lot of work with document stuff. Version 16.04.3 KDE Frameworks 5.28.0 Qt 5.6.1 (kompiliert gegen 5.6.1) kde-thumbnailer-openoffice and kdegraphics-thumbnailers installed.
You need to install Calligra 3.0 (it was recently released). Also, don't forget to enable those previews in the Dolphin settings.
Okay, I tried to find the new version on kubuntu backport ppa, but couldn't find them so far. Is there any date, when it will be released, or any other way to install the 3.0 on kubuntu 16.04? Thanks....
There is no need to install the full Calligra 3.0, but the OpenDocument thumbnailer needs to be compiled as a KF5 version, otherwise Dolphin will not use them. https://store.kde.org/content/show.php?content=110864 has a patch from an openSUSE developer. I suggest to report this issue to the bug tracker of your distribution, asking them to apply that patch.

Re-opening; we can fix this in KDE land.
