chroot_execute: command not found (Debian 11 and Debian 12)

[falxen]

I booted into Hetzner's rescue mode, ran the openzfs_install command (in a different iteration I tried zfs), then apt update && apt upgrade and finally ran this script. I did that for both Debian 11 and Debian 12, and I got the chroot_execute error in both cases. Unfortunately the script proceeds despite that failure, and finally goes on to reboot.

P.S. I also got the same error with Ubuntu 22.04 in Hetzner's rescue system
