libyang2 2.0.112-6ubuntu2 (arm64 binary) in ubuntu lunar

 Libyang implements functions to process schemas expressed in the
 YANG data modeling language defined by the IETF in RFCs 6020/7950.
 Schemas expressed in this language primarily describe configuration
 used by larger network equipment like routers and switches.
 .
 In addition to handling the schemas itself, the library also provides
 functions to process data described by the schemas.
 .
 The library is implemented in C and provides an API for other software
 to use in processing configurations.
