Package: live-build Version: 1:20191221 Followup-For: Bug #961257 I just realized that live-build version in testing and sid (package version 1:20191221 ), doesnt't have files for --distribution bullseye either.
Making a symlink bullseye -> squeeze in /usr/share/live/build/data/debian-cd did help resolve the issue for me, and --distribution bullseye looks to be working. Same could be made by default for 'testing'.
