impossible to launch on xubuntu appimages, that work on gnome

Hello
I have a problem launching my appimages on xfce/xubuntu desktops

libfuse2 is installed, the appimages files are executable. When I run the files, nothing launches.

What perplexes me is that, if I launch gnome, everything works perfectly.

I am on a freshly installed and update Ubuntu 24.04.1 LTS, xfce/xubuntu was installed using the xubuntu-desktop package (and its dependencies).

Hello and welcome.

How are you launching/running the app images?

Re: impossible to launch on xubuntu appimages, that work on gnome

I just read a thread on the Siduction forum about some mix match libraries with appimages. I doubt that's your issue if it run under Gnome though. Possibly a services issue?

Settings>>Sessions and Startup>>Advanced Tab>>Check Launch Gnome services on startup

Hello and welcome.

How are you launching/running the app images?

right click then run ( execute)

when i run it in a terminal
[11621:1105/005050.041984:FATAL:setuid_sandbox_host.cc(158)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_LM_StuwS29T2/chrome-sandbox is owned by root and has mode 4755.

sudo chmod 4755 /tmp/.mount_LM_StuwS29T2/chrome-sandbox
[sudo] Captain password:
chmod: cannot access '/tmp/.mount_LM_StuwS29T2/chrome-sandbox': No such file or directory

Hello, thank you again for your time and help in solving my problem.

using --no-sandbox poses a very big security problem, it is an option to use only for development.

I have been using Linux for 25 years for stability and security, I prefer to do without an application than to jeopardize that, or simply abandon xfce with regret

sudo chown root:root chrome-sandbox
sudo chmod 4755 chrome-sandbox

Yes I did the test and the response to the commands is: cannot access 'chrome-sandbox': No such file or folder

Added later 10 min 01 s:
The only working solution I found, but it is non-persistent and also not very secure:

sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0
sudo sysctl -w kernel.apparmor_restrict_unprivileged_unconfined=0
