Well spotted. With 'dbconfig-no-thanks', there exists no debconf entry 'mailman3/database-type'. The best solution I can think of, is to ignore errors this way in the mailman3.config maintainer script: db_get mailman3/database-type || true The fix is already in the Git packaging repo and will be uploaded shortly.
