Did you download your install media from the image customizer at https://incusos-customizer.linuxcontainers.org ?
The error you’re getting would be consistent with someone booting an empty ISO image like the one found at Index of /os/
I downloaded it from herehttps://images.linuxcontainers.org/os/202511070055/x86_64/
Yeah, don’t do that. Please follow the instructions:
Very bad https://incusos-customizer.linuxcontainers.org The generated image cannot be downloaded in China
Okay, then you’ll need to build and use the flasher-tool as described in the guide.
That’s it. Thank you.
