Linux installation: GUI says success, stderr says CRITICAL

[jakesalomon]

Greetings.

My previous thread (which is not quite resolved) is still open.  However, I am trying it on Linux, where Acronis is not an issue.

As per the video that told be about ventoy, I downloaded and uncompressed & untarred release 1.0.88, opened a terminal window and then ran: 

Code:

sudo ./VentoyGUI.x86_64

The GUI behaved nicely and claimed success at the installation.  However, back to the shell window I see this pair of messages:

Code:

(Ventoy2Disk.gtk3:2251): Gtk-CRITICAL **: 08:56:33.446: gtk_widget_grab_default: assertion 'gtk_widget_get_can_default (widget)' failed

(Ventoy2Disk.gtk3:2251): Gtk-CRITICAL **: 08:56:33.446: gtk_widget_grab_default: assertion 'gtk_widget_get_can_default (widget)' failed

So did it fail or succeed?  Well, when I insert the USB drive again, I do see it on the desktop.  However, when I open it I see nothing.  The bottom border tells me:
0 items, Free space 64.1GB. HMM.. Since it's mounted on /media/jake/Ventoy, let's peek in with ls:

Code:

ls -lda /media/jake/Ventoy/*

ls: cannot access '/media/jake/Ventoy/*': No such file or directory

Not even a boot partition?  I suppose it's a success in that it didn't brick the USB.  But it didn't do anything useful either! 

Wazzup? 

Open to ideas here, folks.

Thanks much for help.
