Debian Bookworm is the contemporary of Ubuntu Jammy, but there's always the possibility that Bookworm will roll forward to a new GLIBC that is unavailable in Jammy. We have the option now, or later, to switch Jammy's build to the predecessor, Debian Bullseye, which will always have a compatible GLIBC, but may introduce other OS differences.

what's the advantage of change the base image? it sounds like ubuntu is the safer bet?

It allows us to use Debian MultiArch which is not available in Ubuntu (binary deps not available for foreign archs). This leads to a simpler cross-compile environment setup that's easy to express in a Dockerfile while remaining compatible with Ubuntu.

is this why you switched to Debian?

Yes. You can add foreign arch in Ubuntu, but apt update breaks immediately, and adding a new repo sources list for Ubuntu ports doesn't unbreak apt update.
