Here's a quick summary of the btrbk dependencies: all versions of btrbk >= 0.23.0 require btrfs-progs >= 3.18.2
btrbk-0.25.0 supports ALL versions of btrfs-progs <= 4.11.1 btrbk-0.25.1 supports ALL versions of btrfs-progs <= 4.13.1 btrbk-0.26.0 supports ALL versions of btrfs-progs >= 3.18.2 > To prevent this, please provide a bpo of btrbk-0.25.1. Unfortunately I'm not a debian user myself and don't know much about all this. If I understand it correctly, this is not needed now?
