Bug#1033482: also here

[Paolo Greppi]

Hi, I have tripped onto this while following blindly the automatic 
sbuild setup using sbuild-debian-developer-setup described here:
https://wiki.debian.org/sbuild#Automatic_setup_using_sbuild-debian-developer-setup
Alberto's workaround (sudo apt install -t bookworm-backports 
debootstrap) worked for me.
