Digikam shows an error message "Could not launch the KDE Help Center: Could not find service 'khelpcenter'." when starting it in Ubuntu Unity desktop. If this service is not available when not running KDE, would it be possible to open a HTML version of the Digikam handbook in a browser, either online or locally? Reproducible: Always Steps to Reproduce: Start Digikam in Ubuntu Unity desktop (or Lubuntu desktop, or anything non-KDE I guess) Click on "Help > Digikam Handbook" Actual Results: Digikam shows an error message "Could not launch the KDE Help Center: Could not find service 'khelpcenter'." when starting it in Ubuntu Unity desktop. Expected Results: Digikam should *somehow* display its handbook (external browser, manual start of khelpcenter, etc.) This is not a major bug, but it's a major usability issue for the default desktop on the most common Linux distribution. Plus there's an easy fix (start khelpcenter manually, or start a web browser with the handbook).
Help depend of this KDE part to run. just install it. Gilles Caulier
So true. Sorry ... :(
This problem do not exist with next 5.7.0 as the handbook is open now with online version through an embed web browser based on QtWebView Gilles Caulier
