python3-ospd 21.4.4-1 (amd64 binary) in ubuntu lunar

 This package contains a base class for security scanner wrappers which share
 the same communication protocol: OSP (Open Scanner Protocol). OSP creates a
 unified interface for different security scanners and makes their control flow
 and scan results consistently available under the central Greenbone
 Vulnerability Manager service.
 .
 OSP is similar in many ways to GMP (Greenbone Management Protocol): XML-based,
 stateless and non-permanent connection.
 .
 The design supports wrapping arbitrary scanners with same protocol OSP,
 sharing the core daemon options while adding scanner specific parameters and
 options.
