KDE KIO client error, The file or folder does not exist

Hi, I have a problem on some installations of a Linux distribution with Duplicati pre-installed. It is a Debian 11 based distribution with KDE Plasma. Well, once the system is started, when I click on the Duplicati icon to start the program it gives the following error: “Error - KIO Client The file or folder http://localhost:8200/index.html does not exist”. If I open a browser and type this address, Duplicati opens and works correctly. The problem is that the system is not able to open the application in a web browser. I have Firefox as my default browser.
Thanks for your help

If it works in the browser, that means it is running. Maybe the pre-configured shortcut is wrong (tries to open a file instead of a browser)? That might be an issue with your distribution and the way it is set up, usually the shortcuts are defined in a file somewhere.

It might also be duplicati trying to open the browser and failing, that would be a different problem.

Do you mean the Duplicati Tray Icon in system tray, or some other icon, perhaps something static?

So some work, and some don’t? Any ideas on how they differ? My Google searching is a dead-end.

I didn’t know there was such a thing. Who created it? It might be necessary to find out what you got.

Thank you very much for your response.
The Duplicati icon in the start menu does not work.
The Free Software Office of the University of Zaragoza publishes and maintains the GLUZ distribution which includes Duplicati as one of the pre-installed applications of the distribution.
At the University of Zaragoza we like Duplicati and we are working on its implementation in the teams of professors and other staff.
You can download GLUZ at Index of /osluz/gluz/3


FYI I have a VM with Kubuntu 22.04 (based on Ubuntu 22.04 of course) and Duplicati icon works fine here so it’s not a problem with Kde. I will assume that the shortcut must be identical for your distro and just starts duplicati, so working from here check that your duplicati start script (which duplicati) looks like that:



and verify that your Duplicati is the original provided by the project, not a recompiled version, so check that dpkg -l | grep duplicati returns and that apt-cache show duplicati output contains:

Edit: oops, should be
