The second part here does nothing: you can place any other file name and
it still exits successfully.

Looking at an strace, I think ‘--appimage-extract’ does next to nothing:
essentially it reads /proc/self/exe, create an empty “squashfs-root”
directory, and exits.

Could you check exactly what’s happening?

We’re getting really close!

Thanks,
Ludo’.
