[BUG] Desktop icons failing to launch in webtop Fedora XFCE 26a7b8ac

[coopervarela]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Ran into an issue when I updated my webtop image to Fedora XFCE 26a7b8ac where I can no longer launch icons from my desktop. When clicking on icons on the desktop I get the error Error: Failed to launch “application name” this feature requires a file manager service to be present (such as the one supplied by Thunar)

Expected Behavior

The expected behavior is a icons within the desktop should launch.

Steps To Reproduce

1. Within the desktop right click and create new file
2. Launch the new file by double clicking on the desktop

Environment

OS: Ubuntu 24.04.1 
How docker service was installed: Apt install
Webtop version: fedora-xfce-26a7b8ac-ls242

Docker creation

docker run -d   --name=webtop21   -e PUID=1000   -e PGID=1000   -e TZ=Etc/UTC   -p 3000:3000   -p 3001:3001   -v /home/cooper/webtop-config:/config   --shm-size="1gb"   --restart unless-stopped   linuxserver/webtop:fedora-xfce-26a7b8ac-ls242

Thanks for opening your first issue here! Be sure to follow the relevant issue templates, or risk having this issue marked as invalid.

Just did some initial digging running xfdesktop in the foreground and verbose session logging. Nothing is logged when this occurs and you also cannot drag stuff from the application launcher onto the desktop.
It seems like a bad interaction when real dbus is not working, xfdesktop is trying to communicate with thunar --daemon via dbus and failing and not falling back to anything.

I am not 100% sure I can fix this.

This happens on arch-xfce and el-xfce as well, but not on Alpine, Ubuntu, or Debian.

If you can I would just swap parent flavor unless you need rpm for something specific in that case use mate or KDE.

[the-real-jeremy-coleman]

Any updates on this issue?

It seems somehow related to Thunar not being found by xfdesktop. I don't know enough about dbus interactions to chase that thread. In the case of EL image variations, Thunar is not installed since caja is the default filemanager. With Fedora the Thunar binary gets relocated. I assume this is somehow related to the image security posture and maybe PROOT, but haven't had a chance to read about what is going on re: relocating exo-open and Thunar. Desktop Application Shortcuts work properly for me with the following workarounds.

EL XFCE image:
Build a new container with the following Dockerfile.

FROM linuxserver/webtop:el-xfce
RUN \
  echo "**** install packages ****" && \
  dnf install -y --setopt=install_weak_deps=False \
    Thunar

Fedora XFCE Image:
Reverse the relocation of Thunar that happens in the current Dockerfile.

FROM linuxserver/webtop:fedora-xfce
RUN \
  echo "Reinstating Thunar Binary" && \
    mv \
      /usr/bin/thunar-real \
      /usr/bin/thunar

[thelamer]

I need to build webtop tomorrow, I will take a look at reverting these thunar wrappers if they are not needed anymore

[thelamer]

Resolved in latest, it looks like head thunar this is not needed anymore, arch does not need the wrapper anymore as well.
