Install is failing on a new Raspberry Pi

I'm trying to move my backup scripts from one Pi to another. The old one was running Ubuntu, the new one is running Debian Bullseye. I must be doing something silly or missing something obvious.

Is your raspberry Pi running a 64 bit operating system?
What do you get for ldd ./bb?

It's an old Pi 4 that just been updated to a later Raspbian. I had forgotten that those are 32 bit. I'll just put Ubuntu on this one. Thank you!
