Engine died unexpectedly without sending output: status 127

[freysgodi]

I have a bug report

hw: lenovo thinkpad, 32 gb ram, nvidia gm206glm
os manjaro kernel 6.14.6-2
python 3.13.3

katrain installed through pipx (it run successfully under win10)

console output:

Using user config file /home/$$$$$$$$$$/.katrain/config.json
This doesn't look like a squashfs image.
ERROR: Unexpected exception Expecting value: line 1 column 1 (char 0) while processing KataGo output b'Cannot mount AppImage, please check your FUSE setup.'
