Hello Gilles,<br>
<br>
thanks for the fast response. But unfortunately, it does not work as
described in the how-to:<br>
<br>
When I call "./squashfs-root/AppRun debug" it does not show within
30 seconds a command line to attach the debugger. Output is more or
less same as before:<br>
<br>
<pre>$ ./squashfs-root/AppRun debug
-- digiKam Linux AppImage Bundle
-- Use 'help' as CLI argument to know all available options for digiKam application.
-- Notes: to integrate this bundle to your desktop, use AppImageLauncher.
-- to enable all debug messages on the console, use 'export QT_LOGGING_RULES="digikam*=true"'.
-- to extract the bundle contents locally, use option '--appimage-extract' on the command line.

Within that call following window appears:<br>
<img src="cid:part1.901mJaJ1.LhI6JgI3@wolter.re" alt=""><br>
<br>
Clicking on "OK" has no effect, the windows remains as it is. The
mentioned location of the digikam DBs is correct.<br>
What is meant with the configuration file in the red box?<br>
My config files are located under ~/.config:<br>

Can I provide you further information to nail down the problem?<br>

Download the "-debug" suffixed appimage bundle that we provide and run
it in GDB as explained here :

At end, list the GDB backtrace here for investigation.
Note : the both awk error at startup are suspect:
awk: read error (Is a directory)

AppImage start through a bash script internally which can be viewed here :
