The Pi board was created after the Patchbox OS image was built.
One solution could be to copy the contents of /boot/ partition of a new Raspberry Pi OS (legacy arm) build on top of the /boot/ partition of Patchbox OS - it may make it boot successfully.
Another solution could be if you have an older Raspberry Pi model like 3B+, boot Patchbox OS on it, run
sudo apt update && sudo apt upgrade to get the kernel upgraded to the latest version, then shutdown and put the SD card into the latest Pi board.
Third solution could be to actually use Raspberry Pi OS (legacy arm), add our APT repository (https://apt.blokas.io/), and run
sudo apt update && sudo apt install -y blokas-jack patchbox-cli, afterwards run
patchbox to set up the system. (Patchbox OS is based on Raspberry Pi OS lite, just a couple of packages are preinstalled, different username and a couple of cosmetic changes )
