Package: btrfs-progs Version: 4.12-1 Severity: important As of btrfs-progs-v4.12, the "btrfs subvolume show" command changed its output format, breaking btrbk. While this has been fixed in btrbk-0.25.1, all versions of btrbk <= 0.25.0 exit with error, and are not able to create desired snapshots and/or backups.
See: https://github.com/digint/btrbk/issues/172 I suggest adding "Breaks: btrbk (<= 0.25.0)" to btrfs-progs-4.12
